This week, Covid-19 passed heart disease and cancer as the leading cause of death per day in the United States. In this graph made by Dr. Maria Danilychev using data from Worldometer and the CDC, you can see that Covid-19 overtook heart disease sometime on Monday or Tuesday.
If the data in NYC is any indication, the number of nationwide Covid-19 deaths may be undercounted, so this transition probably happened sooner.1 Hopefully through the social distancing and other measures put in place to flatten the curve, the number of daily Covid-19 deaths won’t start beating out all other causes combined before it starts declining.
Since 2008, the Hedonometer has been tracking the language we use on Twitter to assign a daily score that measures how collectively happy we are (English tweets only). From the data, you can see that happiness spikes on holidays & after notable news events (same-sex marriage legalization) and unhappiness follows mass shootings, terrorist events, and Trump’s election. But the Covid-19 pandemic has brought Twitter’s collective happiness rating to an overall new low and its first sustained period of unhappiness.
The day they identify as the unhappiest is March 12, 2020, which is the day after Americans finally took Covid-19 seriously. Within the space of a few hours on March 11, the NBA announced it was suspending its season, Tom Hanks revealed that he and his wife Rita Wilson had Covid-19, the WHO declared Covid-19 a pandemic, Donald Trump went on primetime TV to address the nation, and the DJIA closed down 1400 points (it would drop another 2350 points on Mar 12).
People on Spring Break in Florida for the past couple of weeks were famously unconcerned with social distancing measures implementing in other areas of the country to help stem the tide of COVID-19 infections and save lives. Using cellphone location data from just the phones of the people gathered on a single beach in Fort Lauderdale, Florida, this video shows just how far those people spread across the country when they went home, possibly taking SARS-CoV-2 with them. They go everywhere.
Show of hands: who feels uncomfortable being reminded of the extent to which 3rd party companies know the location of our cellphones? With tools like the one demonstrated in the video & other easily available info, it has to be trivial to identify individuals by name using even “randomized” data and so-called metadata.

The practice of quarantine began during the 14th century, in an effort to protect coastal cities from plague epidemics. Cautious port authorities required ships arriving in Venice from infected ports to sit at anchor for 40 days before landing β the origin of the word quarantine from the Italian “quaranta giorni”, or 40 days.
One of the first instances of relying on geography and statistical analysis was in mid-19th century London, during a cholera outbreak. In 1854, Dr. John Snow came to the conclusion that cholera was spreading via tainted water and decided to display neighborhood mortality data directly on a map. This method revealed a cluster of cases around a specific pump from which people were drawing their water from.
While the interactions created through trade and urban life play a pivotal role, it is also the virulent nature of particular diseases that indicate the trajectory of a pandemic.
One of my big takeaways from the Tracking Infectiousness section of the piece is: holy shit, look at how contagious measles is! An R0 of 16! (The common flu is about 1.5 and ebola is 2.0.) And people want to keep their children from getting vaccinated for this?!
Over the past week or so, echoing public health officials & epidemiologists, I’ve been trying to illustrate the often counterintuitive concept of exponential growth that you see in an epidemic and how flattening the curve can help keep people healthy and alive. But I think people have a hard time grasping what that means, personally, to them. Like, what’s one person in the face of a pandemic?
Well, epidemiologist Britta Jewell had a similar thought and came up with this brilliantly simple graph, one of the best I’ve seen in illustrating the power of exponential growth and how we as individuals can affect change:
Jewell explains a bit more about what we’re looking at:
The graph illustrates the results of a thought experiment. It assumes constant 30 percent growth throughout the next month in an epidemic like the one in the U.S. right now, and compares the results of stopping one infection today β by actions such as shifting to online classes, canceling of large events and imposing travel restrictions β versus taking the same action one week from today.
The difference is stark. If you act today, you will have averted four times as many infections in the next month: roughly 2,400 averted infections, versus just 600 if you wait one week. That’s the power of averting just one infection, and obviously we would like to avert more than one.
So that’s 1800 infections averted from the actions of just one person. Assuming a somewhat conservative death rate of 1% for COVID-19, that’s 18 deaths averted. Think about that before you head out to the bar tonight or convene your book group as usual. Your actions have a lot of power in this moment; take care in how you wield it.
Illustrator Jerry M. Wilson has drawn a series of constellations that explore the etymology of the constellations’ names and related words in several languages. So for example, “Taurus” is Latin for “bull”, which is “toro” in Spanish & Italian and “tyr” in Danish. And then you also have associated words like “toreador” (“bullfighter” in Spanish) and “teurastamo” (Finnish for “slaughterhouse”)…a constellation of words related to “Taurus”.
Including some irregular times off, overall it took me four years to visit every single road on the map. When I started this hobby, it took me 30 to 40 minutes to do the route. Later it expanded to 2 hours to get to the office when I tried to reach the furthest places on my map. One of the main goals was never to be late for work. From the beginning, I planned to visit not only the main roads but every single accessible mews, yard, park trail, and a path that was possible to go through. I used Endomondo app to have a proper record of my journeys and proof that I have been there. After every trip, I prepared my next route in Google maps where it was easy to adjust streets to the next ones and mark points to revisit if I missed something.
The arrangement of the sticks in these Marshall Islands navigational charts represents ocean swells & currents and how they interact with the land, useful information for navigating between islands via canoe. From a Smithsonian Magazine article about these charts:
The chart is less a literal representation of the sea, says museum curator and anthropologist Adrienne Kaeppler, and more an abstract illustration of the ways that ocean swells interact with land. Curved sticks, she explains, show where swells are deflected by an island; short, straight strips often indicate currents near islands; longer strips “may indicate the direction in which certain islands are to be found;” and small cowry shells represent the islands themselves.
The stick charts were preparatory & teaching tools β mariners would memorize the charts before heading out to sea rather than take them along on the boat.
The first 30 seconds of this time lapse video provides a great look into how the 10 satellites that make up the Global Precipitation Measurement Constellation scan the surface of the Earth to provide daily global precipitation maps.
This visualization shows the constellation in action, taking precipitation measurements underneath the satellite orbits. As time progresses and the Earth’s surface is covered with measurements, the structure of the Earth’s precipitation becomes clearer, from the constant rainfall patterns along the Equator to the storm fronts in the mid-latitudes. The dynamic nature of the precipitation is revealed as time speeds up and the satellite data swaths merge into a continuous visualization of changing rain and snowfall.
Over a period of three months, Seung Lee knit a blanket showing a visualization of his infant son’s sleep patterns from birth to his first birthday.
The sleep data was collected with the BabyConnect app which lets you export to CSV. The CSVs were filtered and converted into JSON (using Google Apps Script and Python) which could then be used for visualization and tracking.

Designer Scott Reinhard takes old geological survey maps and combines them with elevation data to produce these wonderful hybrid topographic maps. From top to bottom, here are Reinhard’s 3D versions of a 1878 USGS Yellowstone map, a 1904 USGS map of Acadia National Park, and a 1899 USGS map of the Grand Tetons.
If you grew up watching TV (and who didn’t?), this bar chart race animation of the 10 most popular primetime TV shows from 1986-2019 is fascinating.
Ranking is based on the following factors: prime-time first 24 hours audience reports, one week of reported statistics for downloaded copies (pirated), one week of streaming services viewership. Numbers are worldwide with significant bias towards US market up until 2002, afterwards it’s balanced by p2p distribution across the globe.
I’d forgotten what a huge hit ER was in the mid-90s. And note that The Simpsons never cracked the top 10. Ah, I didn’t notice that they snuck in briefly during 1996 β thx @ChasingDom. (via waxy)
Each day since the beginning of October, the team of designers, technologists, and researchers at Beautiful News Daily (a project by Information Is Beautiful) have been posting infographics and data visualizations that share some good news about the world. The site’s tagline is “unseen trends, uplifting stats, creative solutions”.
The bad news we see everyday on news websites, newspaper front pages, and magazine covers is important (or can be, if it’s not designed to keep people frightened and hooked on the news), but the good news is just as significant (or can be, if it doesn’t cause you to forget the world’s true suffering and turmoil).
It’s easy to get started with chart.xkcd. All that’s required is the script included in your page along with a single
You can use it to make line charts, XY charts, bar charts, radar charts, and pie/doughnut charts. I am definitely going to be using this in the future.
Moon dust may not burn you, but it’s no picnic. Like Earth sand, moon dust is effectively made of tiny glass shards, but the sharp edges have not been worn down by erosion. As a result, it can be pretty unhealthy.
From the American Museum of Natural History in NYC, an animated timeline of human evolution, from when hominins first show up in the fossil record in Africa some seven million years ago to the appearance of Homo sapiens about 200,000 years ago. You can see artifacts and fossil remains of many of the hominins at the museum in the Hall of Human Origins. I haven’t been there in awhile…might be time for a visit.
I got this from Open Culture, where Colin Marshall goes into more detail:
And though hominins may have walked upright, they also climbed trees, but eventually lost the grasping feet needed to do so. Later they compensated with the very human-like development of making and using stone tools. Two million years ago, the well-known Homo erectus, with their large brains, long legs, and dextrous hands, made the famous migration out of Africa.
We know that by 1.2 million years thereafter Homo erectus’ brains had grown larger still, fueled by new cooking techniques. Only about 200,000 years ago do we, Homo sapiens, enter the picture, but not long after, we interbreed with the various hominin species already in existence as we spread outward to fill “every geographic niche” of the Earth.
The last bit of the video was unexpectedly sobering:
Homo sapiens were highly adaptable, quickly filling nearly every geographic niche. Other hominins went extinct. Climate pressures and competition with Homo sapiens may have wiped them out.
If we don’t change our ways soon, one way to look at the recent history of life on Earth is that modern humans came along 200,000 years ago and systematically conquered and killed the all of the animals on the planet larger than an ant. Not such a great deal for anything but people.
In 1965, Intel co-founder Gordon Moore predicted that the number of transistors in dense integrated circuits would double each year for the next decade. In 1975, he revised his prediction to a doubling once every two years. And for the past 45 years, Moore’s Law has more or less held. This clever bar chart race visualization shows Moore’s prediction competing through the years with hundreds of real microprocessors, from Intel’s 4004 in 1971 to 2019’s newest CPUs and GPUs.
Check out the lull in the 90s, where the microprocessor industry falls behind Moore’s Law all the way from Intel’s 486 in 1989 to the release of Intel’s Itanium 2 McKinley chip in 2002. And then in the 00s, the chipmakers put their foot on the gas again, more than doubling up on Moore’s Law at times. I wonder if the 90s slump was due more to a lack of industry competition against Intel’s near monopoly…they simply didn’t need to increase the count as quickly with no real competitors breathing down their necks. Then in the 00s, competition flourished. If so, perhaps Moore’s Law should be regarded as just as much of a business prediction (or goal) as one about technology.
In 1936, former director of research at the Cleveland Federal Reserve L. Merle Hostetler published 75 Yrs. of American Finance, a hand-drawn chart of the economic health of the US from 1861 to 1935. The chart, which is horizontally oriented, shows a trending business activity index (which measures productivity) along with other financial data, indicates when Congress is in session, lists notable news events, and shows the high and low of the DJIA (starting in 1898). The graphic at the top shows Hostetler’s chart from 1929-1931, aka the beginning of the Great Depression.
The copy of this chart hosted by the St. Louis Fed goes to 1938…it must have been updated at some point. Also, if you go into the “Β»” menu in the upper-right corner of the in-page document viewer, you can set it to “horizontal scrolling” for easier viewing. (thx, andy)
As you can see from the charts, the usage of many parks is heaviest in the summer. For instance, Yellowstone is used heavily until the beginning of September and then drops off to almost nothing by mid-October. For some parks, like the Great Smoky Mountains and Shenandoah, usage spikes in the fall during peak foliage.1
In today’s episode of Earworm, Estelle Caswell teams up with Matt Daniels from The Pudding to track the popularity of the falsetto in pop music from the 50s to today. Caswell has a hunch that falsetto has been getting more popular, so they end up getting a bunch of data from Pandora that tracks the amount of falsetto used in a song and the vocal register of the singer, which they compared against Billboard Top 100 songs. The verdict? You’ll have to watch the video, but just remember all of those soul songs in the 70s and heavy metal & pop songs in the 80s…
By reputation the falsetto voice is both angelic and diabolical, depending on who is singing, and to what purpose. JΓ³nsi Birgisson, vocalist with Sigur RΓ³s, is revered for his keening falsetto, the most ethereal element inside a great wash of sound. Birgisson is openly gay; on the other hand I still remember, at age 13, hearing Robert Plant singing Led Zeppelin’s ‘Black Dog’ (1971) for the first time, and how its devilish heterosexual lust scared me to bits. Plant is a truly outrageous singer, possessing a voice so alight with desire that he sounds in imminent danger of burning up. He is predatory but vulnerable, a bare-chested rock god who sings from a place of sexual rapture that cancels out the boundaries of his own body. He got there through intensive study of the blues: as with most tropes in popular music, the falsetto is in continual transit between black and white performers and their audiences.
But back to the video, I LOL’d at ~3:30 when they went through the raw data of falsettos, which goes from George P. Watson in 1911 (a yodeler) to contemporary Radiohead. I am a big Radiohead fan. And my kids? Not so much. In fact, my son has been trying to convince me for the past year that Thom Yorke doesn’t so much sing as yodel. I’ve explained falsettos to him but I will invariably hear “ugh, yodeling!” from the backseat when Radiohead comes on in the car. This Watson/Radiohead connection though…maybe he has a point? Maybe I just like yodeling?
Every few seconds, the visualization picks a new satellite to track, allowing you to see the location, height, and speed. The satellites are 300 miles from the surface of the Earth moving at about 17,000 mph.
The Andrews brothers travel the world taking overhead drone photos that they offer as prints on their site Abstract Aerial Art. I was especially struck by this photo of a container ship, whose shadow doubles as a graph of how tall each row’s containers are.
With the 50th anniversary of the first crewed landing on the Moon fast approaching, I thought I’d share one of my favorite views of the Moon walk, a map of where Neil Armstrong and Buzz Aldrin walked on the Moon, superimposed over a baseball field (bigger). The Lunar Module is parked on the pitcher’s mound and you can see where the two astronauts walked, set up cameras, collected samples, and did experiments.
This map easily illustrates something you don’t get from watching video of the Moon walk: just how close the astronauts stayed to the LM and how small an area they covered during their 2 and 1/2 hours on the surface. The crew had spent 75+ hours flying 234,000 miles to the Moon and when they finally got out onto the surface, they barely left the infield! On his longest walk, Armstrong ventured into center field about 200 feet from the mound, not even far enough to reach the warning track in most major league parks. In fact, the length of Armstrong’s walk fell far short of the 363-foot length of the Saturn V rocket that carried him to the Moon and all of their activity could fit neatly into a soccer pitch (bigger):
Astronauts on subsequent missions ventured much further. The Apollo 12 crew ventured 600 feet from the LM on their second walk of the mission. The Apollo 14 crew walked almost a mile. After the Lunar Rover entered the mix, excursions up to 7 miles during EVAs that lasted for more than 7 hours at a time became common.
As you should know by now, I am a sucker for 19th century infographics. This “compendious chart” from the Library of Congress shows the distances and compass directions of about 1300 cities from the central point of Washington DC. You can zoom in on the chart to check out the detail:
The map doesn’t say what the colors signify β there’s also a black & white version β but it was created in 1827 so perhaps they denote the three parts of the country at the time: yellow is the North, pink is the South, and green is the West.
Using temperature data from around the world, climate scientist Ed Hawkins has built a tool for viewing the “climate stripes” for almost any location, a data visualization that represents the change in temperature over time over the past 100+ years. For most locations, the graphs shift from blues to oranges & reds as the climate warms, neatly illustrated by the global graph:
Here’s Vermont (where I live) and Arizona:
You can see there’s more variation on the regional level than globally. Check out the graph for Mississippi:
At The Paris Review, historian Ted Widmer highlights the work of Emma Willard, pioneering educator and America’s first female mapmaker. Willard began her mapmaking career in the 1820s.
She used every tool available to teach young readers (and especially young women) how to see history in creative new ways. If the available textbooks were tedious (and they were), she would write better ones. If they lacked illustrations, she would provide them. If maps would help, so be it: she would fill in that gap as well. She worked with engravers and printers to get it done. She was finding her way forward in a male-dominated world, with no map to guide her. So she made one herself.
The maps for sale show North America in twelve different snapshots. I say “snapshots” because Willard was such an inventive visual thinker. On the eve of photography, she was thinking hard about how to capture a big story inside a single striking image.
It takes some imagination, but standing before a painting by Hilma af Klint, a sculpture by Bernini, or a cave painting in Chauvet, France draws you back in time in a powerful way: you know you’re standing precisely where those artists stood hundreds or even thousands of years ago, laying paint to surface or chisel to stone. Even experiencing art through prints or photographs leads the mind to consider all the cultural, political, technological, and economic things that were happening when the work was produced. Art is a doorway to past worlds.
Fisk’s maps represent the memory of a mighty river, with thousands of years of course changes compressed into a single image by a clever mapmaker with an artistic eye. Looking at them, you’re invited to imagine the Mississippi as it was during the European exploration of the Americas in the 1500s, during the Cahokia civilization in the 1200s (when this city’s population matched London’s), when the first humans came upon the river more than 12,000 years ago, and even back to before humans, when mammoths, camels, dire wolves, and giant beavers roamed the land and gazed upon the river.
I don’t know if this needs a disclaimer or not, but 20x200 paid me a modest amount to write this blog post for their site but not the post you’re reading now. 20x200 didn’t pay me to write this here post; they didn’t even ask me if I would link to their post from my site. I once wrote a slightly longer (and progressively unhinged) disclaimer for a previous post about 20x200.
Over the past year and a half I’ve been working on a collection of ten maps on planets, moons, and outer space. To name a few, I’ve made an animated map of the seasons on Earth, a map of Mars geology, and a map of everything in the solar system bigger than 10km.
As promised, Lutz has posted the source code for each project to her GitHub account: Mercury topography, asteroid orbits. What a great resource for aspiring data visualization designers. Stay tuned to her site, Twitter, or Tumblr for upcoming installments of the atlas.
This week’s map shows every single star visible from Earth, on the darkest night with the clearest sky. The map also includes all of the brightest galaxies, nebulae, and star clusters from W.H. Finlay’s Concise Catalog of Deep-sky Objects. I illustrated the familiar Western star patterns β or asterisms β in blue and gold, as well as the scientific constellation boundaries in red.
Update: Holy moly, I think Lutz’s Topographic Map of Mars might be her most beautiful one yet.
Update: I couldn’t keep up with all of Lutz’s additions to her atlas. You can check out all of the installments in the archive, including the last part (for now), The Geology of the Moon.
