Almost a year and a half ago, Infochimps, the data repository slash marketplace, released a giant scrape of Twitter data representing 2.7 million users, 10 million tweets, and 58 million connections. Twitter soon requested that they take it down while they figured out how they wanted to handle licensing, privacy, etc.

That was in 2008, before Twitter really started booming. Fast forward to now. Twitter and Infochimps have figured out what they want to do, and the Twitter census data is back up. It’s no longer a measly 2.7 million users anymore though. The population has grown to 35 million.

It’s finally here. Indiemapper brings easy and flexible thematic mapping online. I’ve been looking forward to this app ever since I got a glimpse of what was to come over a year ago, through the eyes of Indieprojector. The guys at Axis Maps have taken the core functionality of advanced GIS, simplified the work flow with a well-designed interface, and made it it super easy to create beautiful maps.

In reference to the above, Gen. Stanley A. McChrystal, leader of the American and NATO forces in Afghanistan, joked during a meeting, “When we understand that slide, we’ll have won the war.” The rest of the NYT article goes on to describe the suck that is Powerpoint.

Is Powerpoint really that bad though? I know we like to poke fun sometimes, but is it a limitation of the software, or is it users’ lack of design skills? I mean there’s a site dedicated to beautiful slide decks. Browse through those, and you start to think maybe it’s the latter.

So we have a chicken-and-the-egg problem. Do people just not know how to use Powerpoint or does Powerpoint push people to the bad side? Sound off in the comments below.

Stephen Von Worley’s Weather Sealed is one of my new favorites. In his most recent graphic, income tax brackets for individuals are displayed.

Air traffic has returned to normal levels in northern Europe, and planes fill up the sky once again. Ito world, who has been doing some great stuff lately, visualizes the reboot of air traffic. We start to see some planes on April 18, and by April 20, everything is back to normal.

There are some holes in the data over France and the Atlantic but you get the idea.

Add another piece to the ever-growing list of Twitter visualizations. What makes Moritz Stefaner’s Revisit different is that it focuses on the conversational threads between Twitter users over time. Tweets (symbolized by authors’ avatars) are stacked vertically and organized by time horizontally. Tweets that have more attention via @mentions are closer to the middle.

Matt McInerney of pixelspread describes the trustworthiness of the people behind their facial hair. You better be careful when I’m around. I’m questionable, border-line unsavory. Don’t worry though. I’m not a werewolf – and I don’t have the ability to grow a Hitler. How trustworthy are you?

Statisticians are mad and out for blood. Someone called R an epic fail and said it wasn’t the next big thing.

I know that R is free and I am actually a Unix fan and think Open Source software is a great idea. However, for me personally and for most users, both individual and organizational, the much greater cost of software is the time it takes to install it, maintain it, learn it and document it. On that, R is an epic fail. It does NOT fit with the way the vast majority of people in the world use computers. The vast majority of people are NOT programmers. They are used to looking at things and clicking on things.

How dare she, right? Here’s the thing. She’s right. Wait, wait, hear me out. For the general audience – the people who use Excel as their analysis tool – R is not for them. In this case, the one that appeals to non-statistician analysts, R, as they say, is an epic fail (and that is the last time I will say that stupid phrase).

However, R wasn’t designed to enable everyday users to dig into data. It was designed to enable statisticians with computing power. It’s a statistical computing language largely based on S, which was developed in the 1970s by the super smart John Chambers of Bell Labs. The 1970s. Weren’t people using slide rules still? Or maybe it was the abacus. Can’t remember. Oh wait, I wasn’t born yet. In any case, there’s really no need to get into the whole R-for-general-audience conversation — just like we don’t need to talk about why The SpongeBob SquarePants Movie lacked emotional depth.

Mapping with R and other free and open-source programs feels clunky and hacked-together at times. The plus-side is that it’s all for free, and once you find the time to wrap your head around it, you can get quite a bit done. Tomislav Hengl provides a free e-book, A Practical Guide to Geostatistical Mapping, that can hopefully help you with such tools (namely R, SAGA GIS, and Google Earth). You can also buy the paperback version on Lulu.

Good Mag put on an infographic contest not too long ago that asked people to design around the idea of neighborhood. Any neighborhood would do, just as long the focus was on local. As you might expect, most of the entries were more design than data, but hey, that doesn’t mean they’re not worth looking at.

A typeface can make or break your graphic. Use Comic Sans, and no one will take you seriously ever again. Luckily, graphic designer Julian Hansen put together this flowchart for a school project to help you figure out what typeface to use. Most of you will probably be interested in the infographic branch.

In another step towards open data and all that jazz, the World Bank released World Development Indicators 2010 today, which is meant to serve as a progress report of the world.

The WDI provides a valuable statistical picture of the world and how far we’ve come in advancing development,” said Justin Yifu Lin, the World Bank’s Chief Economist and the Senior Vice President for Development Economics. “Making this comprehensive data free for all is a dream come true.

More importantly though, this comes with the launch of the freely available online database and public API to 1,000+ indicators. There used to be a big fee for this data. I can’t speak for the API, but the website is well-designed. It has profile pages for each country, links to download the indicators in Excel and XML, and hey, are those graphs implemented in HTML5? I spy <canvas> tags.

Jacobo Zanella makes a color palette every day, based on the clothes he’s wearing.

I observe the colors of the shoes and clothes I wear that day, how much skin is exposed, etc., and reproduce that observation digitally, through RGB combinations. No software or programming is involved in the making of the graphs.

String them all together, and you’ve got multi-colors on top (shirts), a lot of black and blue towards the bottom (pants), and whites and grays all the way on the bottom (shoes).

Too bad he’s not logging it programmatically. That could be an interesting view (well, for him).

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.

Shirt available on Threadless. I seriously need some infographic tees. Too bad the shirt project isn’t still going on. Suggestions, anyone? [via @alternatekev]
