Analyzing Facebook and Twitter updates to gauge happiness is all the rage these days, but Gallup has been doing it old school for the past three years. Every day, Gallup has called 1,000 randomly selected American adults and asked them a series of questions about their well-being such as, “Did you experience feelings of happiness during a lot of the day yesterday?” and “Do you smoke?”

Matthew Bloch and Bill Marsh for the New York Times mapped the responses for the past calendar year. Use the browser to quickly compare well-being in your area and across the country.

We learned the strategy to win Rock-Paper-Scissors every time, but does it really work? For the New York Times, Gabriel Dance and Tom Jackson give you your chance:

Computers mimic human reasoning by building on simple rules and statistical averages. Test your strategy against the computer in this rock-paper-scissors game illustrating basic artificial intelligence. Choose from two different modes: novice, where the computer learns to play from scratch, and veteran, where the computer pits over 200,000 rounds of previous experience against you.

Be sure to play at least five rounds, and then click on the button to see what the computer is thinking. In veteran mode, the computer searches its database for sequences that match your last five moves and its last five moves and then tries to predict what you’ll throw next.

Are you good enough to beat the basic artificial intelligence?

February was a good month. We continue to inch closer towards the 50k-subscriber mark, and traffic-wise we’re nearing that coveted 1M pageviews in a single month. It hasn’t happened yet, but I think it’s going to happen soon, thanks much in part to all of you.

In case you missed these, here are the most popular posts from the past couple of months:

1. Hey Jude flowchart
2. Map of scientific collaboration between researchers
3. What your state is the worst at – United States of shame
4. How Starbucks’ new Trenta compares to your stomach
5. Map of North American English dialects and subdialects
6. Where people swear in the United States
7. A visual guide to eggs
8. Charted guide to fancy drinks

Thanks again for reading and sharing. Every tweet and like helps FD reach a wider audience, so please keep doing it (or doing it more :).

If you’ve ever designed for the Web, you know what a pain it is to get your work to look right in Internet Explorer 6. It’s outdated, and it’s not standards compliant, so a design that looks good in Firefox, Chrome, or Safari might look horrible in IE6 (and subsequent versions for that matter). The good news is that Microsoft has started the countdown to the end with a map that shows IE6 browser share around the world. Twelve percent of the world still uses the browser as of February 2011, with a big chunk of that from China.

Arthur Buxton breaks down van Gogh paintings for a view of color schemes. My instincts tell me you are either loving this or hating it like the black plague.

It’s Friday, and the weekend’s staring you in the face. You look like you need some free stuff. Timeplots has kindly put up three visual history prints up for grabs. In case you’re not familiar, Timeplots takes complex history stories, like the American presidency or the changing nature of the Senate, and puts them in visual form.

Continuing their series on world population, National Geographic focuses in on the “most typical” person in the world. The above image is an artist’s rendering of the average face computed by the Chinese Academy of Sciences in Beijing. Zoom in and you’ll see that the face is made of 7,000 human figures, as shown below. It’s true. I counted.

LEGOs were my favorite toy growing up. This was back when the pieces came in buckets rather than the instruction-filled Star Wars sets that we see nowadays, so it was more about building whatever popped into your head. Good memories. In any case, Samuel Granados took a big ol’ bucket of LEGOs and made some cartograms showing immigration and emigration in the Americas. Each piece represents 10,000 people.

There are no words. More tips on winning in the world found here.

I tweeted this out earlier, but people are really excited about RStudio, an integrated development environment (IDE) that has the potential to make R coding and development a whole lot easier.

As some of you might know, Germany’s defense minister, Karl-Theodor zu Guttenberg, resigned yesterday after admitting that he plagiarized his PhD dissertation. Pitiful, I know.

Gregor Aisch visualized Guttenberg’s dissertation, highlighting the plagiarized portions.

Working off last year’s bracketology graphic, Leonardo Aranda took a simpler approach in showing all the winners and losers from the NCAA tournament from 1985 to present. Each line represents a team (not a school), and championship winners are highlighted blue, so what you get is a quick view of the paths past winners have taken. No schools ranked lower than eight have ever win, and most winners have been seeded in the top three.

I like this version better than last year’s. The sorting is a lot easier to read and understand. What do you think?

The government has been making a big push for more open health-related data, and a couple of weeks ago, they released a whole bunch of it with the launch of HealthData.gov. It’s the same interface as Data.gov, but for health. Additionally, the Health Indicators Warehouse launched with different data and a slightly more useable interface.

A quick scan of the data available, however, does seem to indicate that a lot of it is spotty or outdated (like on data.gov), which doesn’t make it especially useful. For example, some data sets are only one data point, while others are only a single year. At least it’s a start.

iPhone gets all the glory, but there are plenty of Android phones activated every day, worldwide. This quick visualization (below), from the Android Developers themselves, shows just how that growth has gone over the past few years. It starts with a worldwide view and then zooms in on countries for a closer look. Keep an eye on the top left corner for phone launches.

Moki takes a page out of the OkCupid social media playbook and analyzes movie ratings over the past two decades. They looked at the 20 most popular movies for each year, and then plotted them by “polarization,” or rather, standard deviation, or in other words, movies that had a wider spread of ratings were more polarizing than those where reviewers came to a consensus.

WiFi is everywhere, floating and whirling around us somehow, but where is it really? In Immaterials: Light painting WiFi, Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen use a rod of blinking lights to visualize signal strength in their college town.

In order to study the spatial and material qualities of wireless networks, we built a WiFi measuring rod that visualises WiFi signal strength as a bar of lights. When moved through space the rod displays changes in the WiFi signal. Long-exposure photographs of the moving rod reveal cross sections of a network’s signal strength.

The stronger the signal strength, the more lights that illuminate in that specific spot, updating as the walker/carrier moves. Then using long-exposure photographs, the lights are recorded for beautiful results. Super simple concept, yet very effective. See the device in action in the video below.

William Briggs and John Briggs examine the differences between movies that have won Best Picture and those that were top at the Box Office, based on money, gender, age, and genre. “There was only one Oscar winning movie with a leading actress older than 50: Jessica Tandy in Driving Miss Daisy. Eight women were at least 40 in Oscar winning movies, e.g. Myrna Loy, Bette Davis, Sandra Bullock. However, half of these were just 40 or 41.”

Along the same lines of the happiness flowchart, this graphic by Moritz Resl shows a simplified life cycle between happy and sad. Let’s not forget though that sometimes doing stuff you like leads to sad, and more importantly, doing stuff you don’t like can lead to happy. Have a nice weekend!

We saw the true size of Africa, relative to the world’s largest countries, by Kai Krause last year. Taking it in the other direction, xefer shows the true size of Vatican City, world’s smallest state, with an area of approximately 110 acres. That’s just big enough to house a handful of national formations and man-made structures.
