Some people love ’em and others hate ’em. Now you can play with streamgraphs (seen here and here) yourself, whatever side you might be on. Lee Byron has made the code available on Github, under a BSD license.

It’s in Processing, and it’s not plug-n-play like many of you are probably hoping for, but on a quick skim, the code does look very readable and shouldn’t be too hard to grasp for those with a little bit of coding knowledge. I recommend reading Lee and Martin’s streamgraph paper first though.

March 22 was World Water Day, and TreeHugger posted this graphic on drinking water that is available in the world. The main point is that a very small percentage of water in the world is actually drinkable. It’s definitely a story worth telling, but the graphic doesn’t work at all. Even as a simple presentation of percentages (from UN-Water Statistics), it’s confusing.

How can we improve this graphic to tell the story more clearly? Discuss.

GitHub is a large community where coders can collaborate on software development projects. People check code in and out, make edits, etc. Franck Cuny maps this community (with Gephi), based on information in thousands of user profiles.

Design student Kenichi Tanaka animates the history of Japan for his final thesis project.

He pokes fun at his culture a little bit there in the beginning, yeah? I feel like something is getting lost in translation.

Update: The English version was taken down, unfortunately. Here’s the original Japanese version. The graphics are still in English, so you can probably understand most of it without the narration.

The Final Four is just about here. Who’s going to win it all? It’s anyone’s guess at this point, but what we can do while we wait is examine who’s won in the past. Leonardo Aranda takes a gander at who has won in each round since 1985, by ranking, with a color-coded bracket that resembles a stacked area chart.

I think if he used just two colors per corner (instead of entire palettes) and brightness indicating rank, it might be a bit easier to read in the first rounds. At the very least, you could find the Cinderella stories quicker, which is the most exciting part of the tournament a lot of the time.

I still like the concept though. It reminds me of Stephen’s crayon colors.

See the full-sized version here.

Who’s your money on?

In a follow up to Apps for America, Sunlight Labs just introduced their next contest: Design for America.

This 10 week long design and data visualization extravaganza is focused on connecting the talents of art and design communities throughout the country to the wealth of government data now available through bulk data access and APIs, and to help nurture the field of information visualization. Our goal is simple and straightforward — to make government data more accessible and comprehensible to the American public.

There are three subject areas to appeal to different types of designers too. There’s data visualization, process transparency, and redesigning the government for a total of seven challenges each with a $5,000 top prize. Not bad, eh? Visit Sunlight Labs for more details.

By the way, I’m one of the judges (along with Charles Blow, Andrew Vande Moere, Nicholas Felton, and others). You’ve got about two months to show me what you got. Go on, I dare ya.

A few centuries ago, scientists designed the periodic table to organize the elements we knew about in a way that was useful. Elements were grouped by similar properties on the horizontal and vertical. Somewhere down the line, more recently, someone decided to squeeze a different dataset into the same structure. It made very little sense, but it caught on. Maybe because it looked scientific and official. I don’t know.

Now there’s a periodic table of funk, typefaces, candy, and heck, there’s even one for visualization.

So many tables. How do we sort all of them? With another periodic table, of course, and so without further ado, here is the periodic table of periodic tables by Bill Keaggy. Yay?

IBM has been spreading the whole “smarter planet” spiel for a while now, but in the past few days, they’ve revealed the punchline. It’s data. The key to a smarter planet is learning how to process and extract information from the 15 petabytes of data we generate per day.

Surprising? No, not at all. Data’s the hot thing right now, and that’s where the money’s at. Learn how to process all of it and you’re gold.

Spam sucks. We all hate it, but no matter how good the filter, something always seems to get through. Want some cheap Vi4gr4? I can tell you where to get it. New Scientist takes a look at the spamdemic. It costs very little to send tens of thousands of emails, but it only takes a tiny percentage of idiots to make it all worth it for spammers.

Seriously – who falls for these things?

We use visualization for a lot of different things, and its purpose varies person-to-person. Some use it to report the news. Others use it purely for analysis and decision-making. Some even use it for artistic expression. What do you use visualization for? Select the answer that best fits you below. If you select “other,” let us know what that means in the comments.

I didn’t fill out my bracket this year, so it’s not nearly as exciting for me. I don’t think that’s stopped thousands of bars across the country from cleaning house though.

Add another site to the list of places to find the data you need. Data Marketplace connects people who want data to people who can find, scrape, and cull data.

Here’s how it works. If you want data, you put in a request and optionally, a deadline and budget. A provider can then go find that data for you, maybe through scraping a difficult-to-parse website, and then post it online. You then have the option to purchase the tabular data.

There are three big humps to get over though for Data Marketplace to work.
