something in the way

You’ll hear odd cynicism about people working on free software / open source projects. Something like, “well, harumph, it’s not as though a bunch of people will make this stuff in their free time.”

Not only are these folks wrong, but you can actually visualize the contributions to source trees – and the results look spectacularly hypnotic. It’s free software – the music video.

Okay, now, granted, I may get so mesmerized by the results that I’ll just spend time staring at that instead of getting actual work done, but – working too hard isn’t good for you, anyway. It’s an organic high, audiovisuals.

At top, Ryadh Amar sends in a visualization of the excellent, lightweight LXDE windowing environment for Linux. (Actually, I’m inspired to give LXDE a fresh install.) At bottom, a collage of various projects showing that these data visualizations can take on various identities. Gource can support just about any project repository, too: Git, Bazaar (popular on Ubuntu), and Mercurial (recently added to Google Code, incidentally) are available native, and CVS and SVN are available as third-party extensions for those of you kickin’ it oldskool and non-distributed. (Though, really, come join the 21st Century – it’s awesome.)

And Gource can visualize itself. Freaky. It’s all thanks to the ongoing awesomeness of OpenGL.

I’d love to see this added to project management so you’d have a sort of live, superb visual to inspire you to keep the code moving forward.

Who knew source code would turn out to be so visually inspiring? (Now I just need a new way of visualizing me writing bad code and then correcting and cleaning it up. I think it could be best represented as a set of stick figures getting stuck in quicksand and hitting each other over the head. Then there could be a big Smoke Monster that represented the Evil Force of Procrastination.)

But wait! There’s more! You can visualize web logs, too. (It works with Apache; I have to see if I can make it work with our nginx logs, as visualizers could actually be very beneficial with the kind of complex data you get in something like a web log):

I’m in love with the New York Times data visualization/infographics division. They consistently put out some of the most amazing visualization pieces (both in print and online) that I’ve ever seen. Their recently geographic analysis of Netflix ratings was absolutely superb. And we all probably saw their election maps (either for 2008 or 2004). They produce stunning displays that convey amazing amounts of information in a way that only interactive graphics can do. And they’re all done in Flash.

And for even more check out the NYT’s selected infographics list or simply do a Google search for “interactive graphic” on the New York Times website.

So when you see images showing the missing plugin icon on the New York Times website on the iPad or iPhone, that’s not just some annoying ad that’s not playing or a streaming video. That’s some of the most cutting edge visualization work that’s being produced today. And without Flash it simply doesn’t exist.

Sure, you might be able to recreate some of these without using Flash (I’d argue that many you simply would never be able to do, but that’s for another debate). But the point isn’t whether or not you could eventually do it without Flash. The point is that the New York Times does them all with flash. So we need to ask why. It’s not an accident or an arbitrary technology choice. Newspapers operate on a schedule and a budget (and one that is getting tighter and tighter). The simple truth is, creating amazing visualizations like you see on the NYT website is possible and easy with Flash. They use the tools that get the job done most efficiently and produce the best end result. This isn’t an argument about whether it’s theoretically possible to create these types of visualizations without Flash, it’s about whether it’s being done. And save for handfuls of examples, it’s not (for every one good JavaScript visualization I’ll show you ten good Flash ones). Taking away the New York Times’ ability to use Flash is setting their data visualization department back 5 or 10 years. And it would mean that we, as readers and citizens, would be missing out on some of the most important journalism being produced today.

The New York Times (like all newspapers) is in crisis. They are trying to reinvent themselves in an online form. And as a news organization they are one of the most progressive and experimental out there. They are embracing the new medium by doing some of the best damn interactive graphic work I’ve ever seen. They make things that convey news and information in ways that draw people in and keep them coming back for more.

But without Flash they’re just a newspaper. And we all know newspapers are dying.

As I was flying back home into San Francisco airport I was watching the city lights out the window and got struck by a bit of inspiration. I find cities beautiful, from the graffiti to the neon signs to the line of headlights on the highway. A city viewed from above at night is captivating. I wanted to try to recreate that same look, but by visualizing data (in one sense you can say that the real view of a city from above is already a visualization of population data).

I started searching for images of cities at night, and found these amazing images from NASA. All those images were taken from a space shuttle orbiting the earth. These images tell you a lot about the city, the layout, urban density, planning (or lack thereof). I wanted to take other meaningful data and create similar images.

All the visualizations below have been created with SpatialKey. However, this is some experimental work I’ve been playing with to generate the “night light” images, so it’s not released (and might not ever be). Basically this is a peak behind some of the R&D work I do for fun (yes, for a dataviz dork like me making fake “cities at night” images is my idea of fun).

Crime in San Francisco
This image is all crime in San Francisco for a 3-month period. You can see some of the same features that you can see in the NASA space image, such as Golgen Gate Park and the Presidio (the area on the north-west edge of the city). All in all it’s interesting how similar the crime image looks compared to the NASA image. Downtown is the brightest spot in both images, which means that it’s literally the brightest area of the city (the most streetlights), and also has the most crime.

And here are breakdowns for a few different crime types. Notice how different the distributions are. Narcotics crimes are heavily clustered and can be found downtown (in the Tenderloin), in the Mission (near the 16th St BART station), and along Haight Street near Golden Gate Park. Whereas vehicle theft is scattered fairly evenly throughout the city.

Graffiti Reports in San Francisco and New York
Both San Francisco and New York publish their 311 data, which is when citizens call for city services. One category of 311 calls is to report graffiti. Graffiti is interesting in that it often follows specific city streets. When we look at the graffiti data for both cities we see specific streets that have far more graffiti than others. I love these images (particularly the one of SF) because they really look like a view of street lights from a plane.

Trees planted in San Francisco
Another one of my favorites of this set is data for all the trees that the city of San Francisco has planted since 1990 (all this SF data is available at datasf.org). You can see the heavy planting along Market St (which cuts diagonally through downtown), as well as along streets like Sunset Blvd (the street running north/south on the western side of the city).

Street lights (or SF as a giant lite-brite)
One final image of San Francisco we have is the locations of every street light in the city. I liked this image because it reminded me of playing with a Lite-Brite when I was a kid. It almost makes city planning feel light a grown-up version of playing with little plastic lights.
