It was World AIDS Day last week and UNAIDS published the latest estimates on the number of people around the world who are living with HIV. Xaquin G.V. provides four cartograms (i.e. value-aread maps) to show the numbers. In the final result (above) each square represents 10,000 people with HIV, and regions are color-coded by percentage of people with the virus.

This, by Mike Arauz, is just too funny not to post. Sorry, Tiger.

As we all know, David McCandless of Information is Beautiful, launched his new book The Visual Miscellaneum. You can read my review here.

David was kind enough to provide a handful of copies to all of you. How to enter? Just leave a comment at the bottom of this post, and then come back on Monday to see if you’re a winner. If leaving a comment isn’t your thing, because it’s just too crazy hard, you can buy it here. It’s well worth it, and would also make an excellent gift.

Good luck!

David McCandless, author of The Visual MIscellaneum, delves into the usefulness of the H1N1 (swine flu) vaccine. There was quite a bit of research involved, as there’s a crud load of material about H1N1 (naturally).

My wife’s an ER doc, and she says it’s not that big of a deal, seeing as way more people die from the flu, but here’s full graphic. You can decide for yourself.

Statistical graphics are often… kind of bland. But that’s fine, because they’re usually for analysis, and the wireframe does just fine. The time eventually comes though when you need to present your analytical visualization in a paper or some slides, and you’re no longer the primary reader.

In their NYT op-ed on health care calculations, Andrew Gelman, Nate Silver, and Daniel Lee had some graphics of their own that needed some NYT flavor and design treatment.

How has consumer spending changed over the past 25 years? Do we spend more on some things and spend less on other than we did in the early 80s? In this interactive, based on data from the Bureau of Labor Statistics, you can explore just that.

November was another good month. We passed the 25k-subscriber mark for the first time, which to be honest, kind of freaks me out when I think about it, but at the same time it’s of course really cool.

Thanks all for spreading the word, and continuing to tweet, email, and bookmark. A big thanks to those who leave comments on FlowingData too. Your contribution makes this place that much better.

In case you missed them, here are the top posts from November based on a combination of pageviews, comments, and links.

There’s this branch in computer science and statistics for vision research. Normally, if you ever hear about it in the news it’s in the context of spotting terrorists in security tapes or facial recognition checkpoints (you know, like what they have in movies in front of giant steel doors). That is of course not the only application.

Google (and many others) has been playing around with this stuff for a while. Most recently, they released Google Image Swirl in their labs section, which utilizes computer vision to find similar images.

Above is my search for happy cat. The initial search result is what you’re used to. It’s a matrix of thumbnails. Click on one of them, and you’ll get similar images clustered as a network graph.

Google Image Swirl: the new way to find if someone is plagiarizing your work.

I’m no doubt still under massive food coma at this time, but in case you’ve regained consciousness or don’t live in the US, check out this collection of maps from The Morning News. Can you guess what each is supposed to show? If you can guess even one of them correctly, I’ll be impressed.

[Thanks, William]

Straight to the point. It’s Black Friday. Here’s the deal. Get 1 print for the price of 3. No wait, switch that. Get 3 prints for the price of 1 when you buy the series.

Use this code to take advantage: bfridayfps20

This deal ends on Sunday. Get some prints for yourself or as a gift to your data geek friend or dog today.

Remember: your order will help more prints go to local education.

What is FlowingPrints?

For those new to FlowingData, FlowingPrints is a pet project of mine to put data, well, in print. For this first series, I collaborated with two designers to create three original views of education in America – through data. Check ’em out now. They’ll make your walls ridiculously smart.

Food-wise, Thanksgiving is different across the country. In some places you’re going to get a lot of chitterlings and collard greens, while in others, turkey and mashed potatoes. Personally, I’m a big fan of the 10-course Chinese feast, but to each his own.

The New York Times (Matthew Ericson and Amanda Cox), map what’s cooking in your neck of the woods based on searches on Allrecipes. The top search, concentrated in the southeast, was sweet potato casserole. I have no idea what that is, but it must be delicious.

What? I don’t see anything wrong with it.

Verizon has been running these ads lately that compare their 3G coverage to that of AT&T’s. In the ads a Verizon customer walks along on a speedy phone, and a US map pops up that’s covered in red. Later, an AT&T customer looks frustrated with a sparsely-covered AT&T coverage map. You’ve probably seen them by now, but if not, here are the Verizon ones.

This comic was really amusing, although it might be because I’m a big nerd entertained by all things from PHD Comics…

It’s my blog, and I can laugh if I want to.

Have a nice weekend, everyone.

[Thanks, Stephen]

Imagine a world where data becomes the everyday, simply embedded in what you normally do. It’s really not far off if you think about it. We use charts, graphs, and viz to make important decisions with investments, businesses, and to stay informed on the news, so why not use it in our own lives?

Last week I posted some parallel coordinate plots that related SAT scores and class size. Now it’s your turn to take a crack.

You can find the data that I used (and more) from the National Center of Education Statistics. There’s a link to download the data as an Excel file. You can find pupil/teacher ratios here.

The two best entries each win a copy of David McCandless’ The Visual Miscellaneum: A Colorful Guide to the World’s Most Consequential Trivia as well as eternal glory on FlowingData. Yes. Eternal.
