Last week I attended the 29th annual symposium at the Human-Computer Interaction Lab at the University of Maryland. The HCIL is famous for a little thing known as the treemap, created by the founder of the lab, Ben Shneiderman. It’s famous for lots of other visualizations and people too, but it’s best known for the treemap.

The annual symposium is put on by the lab to showcase it’s latest and greatest research. I sometimes forget that HCIL focuses on things other than visualization, so I had to sit, confused, through a few talks before I realized they weren’t about visualization (“Where’s the viz?” I was thinking). I won’t fault them for not being all about dataviz; the Social Network Analysis Strategies for Surviving the Zombie Apocalypse by lab Director, Jen Golbeck, was thoroughly entertaining and insightful work regarding social networks.

John Nelson of IDV Solutions put 56 years worth of tornadoes on a map. John plotted each tornado’s path and used brightness for its F-scale (level of intensity). He also added secondary charts for deaths and injuries and frequency by F-scale.

It makes a gorgeous map. I would love to see the data incorporated into the wind map.

So… practically speaking, if you live in the Midwest or Southern US, you should probably put this on your reading list.

Regardless of your politics, this chart is a great example of how data can tell a story. It’s a very simple graph by the Pew Forum on Religious and Public Life showing the changing attitudes about same-sex marriage. It shows that in the past couple of years, people have begun to be in favor of same-sex marriage.

This Scientific American article by Mark Fischetti and infographic by Jen Christiansen detail the consumption of water usage throughout the world. Jen used a Sankey diagram to show the top 10 water consuming countries and how their water was being used. One of Mark’s first points in the article is that population is the largest factor of water consumption. So I wonder why population adjusted numbers weren’t used. Many of the article’s commenters felt the same way. One posted a few of the countries per capita water use:
China: 2781 lts/day, India: 2591 lts/day, US: 7175 lts/day, Japan: 3752 lts/day

The way you display your data depends on the story you’re trying to tell. In this case, I wonder if the message could be better by using per capita.

Recently there’s been a spate of infographic tools popping up (e.g., easel.ly, venngage, and infogr.am). Okay, I’m not sure if 3 qualifies as a spate, but it sure seemed like a lot in a short period of time. I gave Infogr.am a whirl, and it appears to be the front runner in terms of capabilities. Unlike easel.ly, you can *actually input data* into your infographic! What a novel concept. Venngage was hit and miss in terms of it accepting the data I entered. Infogr.am also has a bug in that you can’t have the number 0 in your data. Go figure.

TileMill is a tool that makes it easy to create interactive maps. Soon they will be adding some new features that will treat maps more like images in terms of modifying the look and feel. This will allow you to apply blending to polygons and GIS data.

AJ Ashton made these examples that are quite compelling, beautiful, and just touch on the possibilities. I can envision many different types of data being drawn with blending techniques as opposed to simply flow diagrams and the like. It will be interesting to see what comes out of these new features.

So I got to thinking, since I’m on this pie chart kick, “what would be the worst pie chart ever?” And I decided it would be a Venn diagram made with pie charts. I laughed to myself, imagining such a creation. Then I thought, somebody’s probably done this. And indeed, there’s an app for that.

At long last, the power of Venn diagrams and pie charts combine to turn the world of mathematics on its head! If you’ve ever felt the need to create Venn diagrams with pie charts, or wished your pie charts could overlap to provide even more informative data, then Venn Pie-agrams is the app for you!

I’ll leave it at that.

Wow, Manuel Lima, Senior UX Designer at Bing, got through a world of information in this 11 minute RSA Animate video. He spoke about the topic for which we all know him – networks. Beginning with the tree as a symbol of relationships (e.g., Aristotle’s Tree of Knowledge), Manuel then quickly sweeps through many concepts through the centuries to finally land on a modern day approach to relational information, the web or network. As trees are no longer capable of representing the complexities of the modern world, we have to find new ways to visualize these structures or perhaps even find a universal structure. His talk is loaded with beautiful examples of trees and networks.

If this fast paced animation is above your processing capacity, you can view the more austere real world video of Manuel instead. It has the bonus of an interesting interview with him in the last 6 minutes.

The OECD’s Better Life Index which debuted last year to much fanfare has been updated with some great new features by Moritz Stefaner.

The concept and beauty of the original piece remain intact. However, the experience is made better by the ability to compare to different demographics. For instance, after I adjust my Better Life settings, I can see how my settings compare to other women my age in the US, or to French men. It’s fun to compare to different people around the world and watch the flowers readjust themselves to the various comparisons. It invokes a sense of global community and humanity.
