I don’t often give in to impulse buys, but I just ordered Cartographies of Time, and I’m pretty sure it’s going to be well worth the thirty bucks.

The Los Angeles Times reports on the chronology of gay rights in the United States. States are colored from fewest to most rights for same-sex couples. “Fewest” means the state bans marriage and legal rights. “Most” means gay marriage is legal in the state. Press play, and watch the changes from 2000 to present. Just disregard the clashing red and green color choices.

In case you’re following the craziness going on over Europe due to that pesky volcano in Iceland, The New York Times provides a tracker for airport closures. The train stations must be packed more than ever before right now.

A big thank you to FlowingData sponsors who help keep the lights on here. As you might have noticed, I’ve been trying something new in the sidebar, and I was lucky enough to have these great groups come along for the ride.

Check out what they have to offer. They make it easier for you to understand your data.

InstantAtlas – Enables information analysts and researchers to create highly-interactive online reporting solutions that combine statistics and map data to improve data visualization, enhance communication, and engage people in more informed decision making.

Tableau Software – Combines data exploration and visual analytics in an easy-to-use data analysis tool you can quickly master. It makes data analysis easy and fun. Customers are working 5 to 20 times faster using Tableau.

Traffic visualizations, mostly in the form of geographic maps, have been popular lately. Governments and organizations have been releasing lots of GPS data, and as a result, we get to see some impressive animations and explore some slick interactives.

We don’t often get to see how cars, trains, subways, airplanes, etc move in physical space, because, well, we’re usually in them, so it’s always interesting to see the big picture. The activity feels very organic as traffic peaks during rush hours and slows down during the night, taxis provide service to and from the airport, and air traffic continues into the late hours. The maps pulsate with energy.

Let’s take a look at some of these great traffic visualizations, some new and some old.

Anyone who’s looked at campaign finance data knows it can get messy really quick (especially if you’re getting it directly from the FEC). Sunlight Labs’ newly launched TransparencyData aims to make the process a lot easier.

They’ve merged state data from FollowTheMoney and federal data from OpenSecrets and made it easy to search with a clickable interface. Select from a number of filters such as amount, recipient, or contributor, and then download data in bulk or make use of the API.

Aaron Koblin (along with Chris Milk) is up to his crowdsourcing mischief again. It started with sheep, then the dollar bill, to a bicycle built for two, and now the Johnny Cash Project. Along the same lines of Aaron’s other projects, viewers are invited to draw an individual frame to the tune of Ain’t No Grave. In the end, drawings are put together to create a whole new music video for the song. Select any illustrated frame to watch a person’s drawing session.

A recent study [pdf] by Sitaram Asur and Bernardo A. Huberman at HP Labs found that it’s possible to use Twitter chatter to predict first-weekend box office revenues simply based on volume of tweets. The predictions were even more accurate when they introduced sentiment analysis (i.e. classified tweets as positive or negative).

If you absolutely refuse to touch any code, I suggest Many Eyes or one of the fine FD sponsors, but if you’re looking to get your hands dirty, Processing is a great place to start.

Jer Thorp, whose work we saw not too long ago, posts this introduction tutorial for data visualization with Processing.

I’m going to start from scratch, work through some examples, and (hopefully) make some interesting stuff. One of the nice things, I think, about this process, is that we’re going to start with fresh, new data – I’m not sure what kind of things we’re going to find once we start to get our hands dirty. This is what is really exciting about data visualization; the chance to find answers to your own, possibly novel questions.

The examples are straightforward, the results are interesting, and most importantly, it gives you a lot to work off of with your own data and geometry. Hopefully it’s the first post of many.

Designer Tiago Cabaco explains the conception of wine in this short animated infographic. Some of the effects, like the frame rotation, are a little overused. It actually made me a little dizzy, but it’s short. Still fun to watch.

Big news. Former IBMers Fernanda Viegas and Martin Wattenberg just announced their new venture Flowing Media (no relation to FlowingData), a consultancy focused on visualization for consumers and mass audiences.

Those who read FD probably already know of the duo, but for those who don’t, I’m sure you’ve seen some of their work. They sit somewhere in between the art/design and technical side of visualization, which always provides for interesting results. I highly recommend them if you’re in need of some viz help. Needless to say, I’m a fan.

Seeing a trend?

This comes just a few months after Ben Fry’s decision to also venture out on his own (after being with Seed for a year). Like Fernanda and Martin, he’s also in Cambridge, interestingly enough. There must be something in the water over there.

If anything, this is yet another indicator of the growing popularity of data, and more importantly, a desire to do something with it. I’m totally guessing here, but I bet Fernanda and Martin’s inbox was chock-full of project possibilities/offers, which I’m sure played a big role in their decision.

I don’t know about you, but I’m excited about the opportunities out there after I graduate. It’s a great time for data scientists.
