Super Bowl tweets mapped

The NY Times has a timeline map showing what people from around the country said on Twitter during the Super Bowl broadcast. I like the emoticons tab but they also should have included a profanity tab.


Music from stock charts

Johannes Kreidler took the data from recent stock charts, fed it to Microsoft Songsmith, and produced melancholy tunes. It’s like the Visualizer in iTunes, only backwards. Ben Fry says of the project:

My opinion of Songsmith is shifting โ€” while it’s generally presented as a laughingstock, catastrophic failure, or if nothing else, a complete embarrassment (especially for its developers slash infomercial actors), it’s really caught the imagination of a lot of people who are creating new things, even if all of them subvert the original intent of the project. (Where the original intent was to… create a tool that would help write a jingle for glow in the dark towels?)


Obama’s personal annual report

Dopplr is doing 2008 personal annual reports for all their users that shows “data, visualisations and factoids” about their 2008 travel. They’ve also done one for Barack Obama on his behalf that you can download for free. Obama took a whopping 234 trips in 2008 and traveled 92% of the distance to the moon!


Pictures of Numbers blog

Pictures of Numbers is infrequently updated, but the subject matter is timeless and the archives are worth a look.

Pictures of Numbers is a book-project-in-progress, consisting of practical tips and techniques for busy researchers on improving their data presentation.


100 Presidential days

A comparison of the words & deeds of the first 100 days of every President since Roosevelt.


Final update to election maps

I added 16 new maps to the 2008 Election Maps page in what is probably the final update. Big thanks to everyone who sent in maps.


Democrats trending upward

Since the 1980 presidential election, more people voted for the Democratic candidate in each successive election than in the previous one…that is, Mondale got more votes than Carter, Dukakis more than Mondale, Clinton more than Dukakis, etc. The vote for Republicans has been a bit more erratic.


The counter-intuitive comparison of all things

The goal of the creators of The Big Chart, The Counter-Intuitive Comparison Institute of North America (CICINA), is to find the single best thing in the world through an NCAA basketball tournament-style bracketing system. This video explains their plans.

Is the Bilbao Guggenheim better than McDonald’s french fries?Are penguins better than Miracle Grow? Can anything beat heated seats on a cold November day?

How many coins?

Earlier this evening, I needed to take some coins that had been piling up to the Coinstar machine. Before I left, I uploaded a photo of the coin bags to Flickr and queried the masses: how much money in the bags?

How did the crowd do? Certainly not as well as the villagers at the 1906 livestock fair visited by Francis Galton.

In 1906 Galton visited a livestock fair and stumbled upon an intriguing contest. An ox was on display, and the villagers were invited to guess the animal’s weight after it was slaughtered and dressed. Nearly 800 gave it a go and, not surprisingly, not one hit the exact mark: 1,198 pounds. Astonishingly, however, the median of those 800 guesses came close โ€” very close indeed. It was 1,208 pounds.

Nate Silver I am not, but after some rudimentary statistical analysis on the coin guesses, it was clear that the mean ($193.88) and median ($171.73) were both way off from the actual value ($426.55). That scatterplot is brutal…there are only a handful of guesses in the right area. But the best guess by a single individual was just 76 cents off.

To be fair, the crowd was likely misinformed. It’s difficult to tell from that photo how fat those bags were โ€” they were bulging โ€” and how many quarters there were.


Touchscreen follies

SNL’s Fred Armisen shows off his interactive touchscreen skills on some political maps of the US.

Check out Michigan…I can make it bounce.

Nice commentary on TV news anchor busywork. See also Anderson Cooper’s magic pie chart. (And sorry, Hulu = US viewers only.)

Update: For non-US viewers, here’s an alternative link that includes the clip in question and a bunch of other stuff. And please don’t yell at me for using Hulu…it’s often the only alternative and it’s relatively easy to watch outside of the US. (thx, nebel)


Mapping newspaper political endorsements

Philip Kromer took the newspaper endorsement data from the Editor and Publisher page I linked to this morning and mapped the results. The states are colored according to FiveThirtyEight’s current projections and those newspapers with larger circulations have larger circles. From Kromer’s blog post:

This seems to speak of why so many on the right feel there’s a MSM bias - 50% of the country is urban, 50% rural, but newspapers are located exclusively in urban areas. So, surprisingly, the major right-leaning papers are all located in parts of the country we consider highly leftish. The urban areas that are the largest are thus both the most liberal and the most likely to have a sizeable conservative target audience.


Tall mountains, long rivers

BibliOdyssey has collected a number of charts which compare the heights of mountains and lengths of rivers by laying them all out next to each other. (Ok, kinda difficult to explain…just go take a look.) I had a chance to buy a copy of one of these maps a few years ago (not sure if it was an original print or what; it looked old) but passed it up because I didn’t have the money. Wish I would have bought it anyway. (via quips)


What are the Japanese up to right now?

As part of the Japanese census, people were asked to keep a record of what they were doing in 15 minute intervals. The data was publicly released and Jonathan Soma took it and graphed the results so that you can see what many Japanese are up to during the course of a normal day.

Sports: Women like swimming, but men eschew the water for productive sports, which is the most important Japanese invention.

Early to bed and early to rise… and early to bed: People start waking up at 5 AM, but are taking naps by 7:30 AM.

Fascinating.


Quirky maps and charts for NYC wayfinding

Christoph Niemann shares a series of his New York City cheatsheets, including tips for getting on and off the subway at the proper points, muffin poking (you know, for checking freshness), and a door opening maneuver called “The Northside Eagle”.

Whenever I rode the subway with my two older boys, I tried to hold on to their hands at all times. In the process, I developed a special move. I think anyone who saw it must have been impressed.

I would hold the boys’ hands as we briskly made our way out of the station, then, just as we reached the turnstiles, I would let go. We would pass through the turnstiles simultaneously, and so smoothly that the boys’ hands would still be up in the air when we got to the other side, where I would grab their little fingers again in one fluid motion. (Requires practice.)

These are great fun.


Stock market charts, in context

Phil Gyford, wearing his finest pair of Tufte trousers, takes a chart of the FTSE that the Guardian ran on Saturday and places it on a scale that shows the fluctuations of Friday’s market compared to the full value of the index.

This particular annoyance is the graphs of share prices in the press and on TV. It is standard practice to start the y-axis at a number much higher than zero, in order to magnify the ups and downs of the market.


Flight pattern maps

A map of the world showing a simulation of all of the air traffic in a 24-hour period. Here’s a higher-quality video. Like Aaron Koblin’s Flight Patterns videos, only not just covering North America.


War and Peace-grade traffic

If you live and work in Los Angeles and have an average commute, you spend 72 hours a year in traffic. That’s enough time to read War and Peace once, get through Wagner’s The Ring Cycle almost five times, or watch the entire Lord of the Rings trilogy almost eight times. The page includes stats for other cities too.

Update: A closer read, a bit of arithmetic, and several emails have convinced me that the 72 hours is not the overall commute time but the time spent sitting motionless in traffic. (thx, everyone)


Star Wars influence chart

A chart from Wired in 2005 shows how Star Wars influenced the later development of movies, games, TV programs, and the like.

The Star Wars empire has grown into one of the most fertile incubators of talent in the worlds of movies (Lucasfilm), visual effects (Industrial Light & Magic), sound (Skywalker Sound), and video games (LucasArts). Along the way, some of the original Lucas crew has gone on to become his biggest competitors.

The Flash interface is really annoying and not useful…the whole image is a better way to look at it. Very Mark Lombardi. (via vc)


Gravestone motif analysis

An analysis of the three major types of gravestone motifs used in eastern Massachusetts during the seventeenth and eighteenth centuries.

The earliest of the three is a winged death’s head, with blank eyes and a grinning visage. Earlier versions are quite ornate, but as time passes, they become less elaborate. Sometime during the eighteenth century โ€” the time varies according to location โ€” the grim death’s head designs are replaced, more or less quickly, by winged cherubs. This design also goes through a gradual simplification of form with time. By the late 1700’s or early 1800’s, again depending on where you are observing, the cherubs are replaced by stones decorated with a willow tree overhanging a pedestaled urn.

Pay special attention to the graph of the popularity of each motif and the slideshow of example gravestones. (thx, peterme)

Update: A reader writes in:

In regards to your post on Gravestone Motif Analysis, I think that the most important text on the subject is still Graven Images: New England Stonecarving and its Symbols, 1650-1815 by Allen Ludwig. It was originally published in 1966, before the article that you linked to. However, Wesleyan University Press published a new edition in 2000 to help meet the rising demands of Material Culture Studies courses. Lots of helpful images and histograms showing the changing patterns of gravestones over that time period.

I *love* that the collective readership of this site knows what the definitive text on New England gravestone carving is. (big thx, fletcher)


Infoviz slideshow

Slate has a nice short history of information visualizations, including work from Josh On, Jonathan Harris, and Martin Wattenberg. Many many more examples can be found on kottke.org’s infoviz page.


2008 movie box office chart

Neat infographic of the 2008 US movie box office. It’s more or less the same as this epic chart from the NY Times earlier in the year.


Stuck in the middle, politically

A very interesting graph of the estimated ideological positions of US voters, senators, and representatives shows that members of Congress are much more liberal and conservative than are US voters, who fall somewhere in the middle. (via 3qd)


Baby Name Trends

For millennia, Martin Wattenberg’s Name Voyager has been the gold standard in cool baby name web doohickeys. No longer…NameTrends gives it a serious run for its money. Lots of slicing and dicing of data going on there. Plus, popularity sparklines.


Smarts on the gridiron

Ben Fry analyzes the data from an intelligence test administered to all incoming NFL players and displays the results by position. Offensive players do better than defensive players on the test, although running backs score the lowest (wide receivers and cornerbacks also don’t do well). As Michael Lewis suggested in The Blind Side, offensive tackles are the smartest players on the field, followed by the centers and then the quarterbacks.

Malcolm Gladwell talked about the Wonderlic test at the New Yorker Conference and judged it a poor indicator of future performance.


Radiohead and Google, together at last

Radiohead + Google + data visualization + lasers = I am contractually obligated to post this. Google has the backstory and some code for Radiohead’s new music video, which was “filmed” using lasers instead of cameras. (via jimray)


Map exaggeration

Exaggerating with maps.

Perhaps most exaggerated of all though has to be the images that are typically given to show the accumulation of “space junk” โ€” remnants of space flights and defunct satellites, etc. In this image each pixel represents approximately 114 miles; so a piece of debris the size of a car is marked with a point the size of Long Island โ€” easily a 6 order of magnitude exaggeration.

Stamen interview

Short interview with Mike Migurski and Tom Carden of Stamen about their projects and process.

We try to start from a position of great abundance and information, to show the vastness or the liveness. I think live, vast, and deep is some of the terminology that we’ve been using lately in a lot of our talks.

Ben Fry has updated his salary vs.

Ben Fry has updated his salary vs. performance chart for the 2008 MLB season that compares team payrolls with winning percentage. The entire payroll of the Florida Marlins appears to be less than what Jason Giambi and A-Rod *each* made last year.
