Venn diagrams are a great way to visualize the structure of set relationships. They’re also an example of a technique that works very well for a particular purpose, but that entirely fails outside its well-defined scope or when the number of sets gets too large.

At their best, information graphics can be informative, exciting, and attractive. At their worst, they can be misleading, overdesigned, and empty. Infographics are still in their infancy, with a lot of untapped potential. Ideas from visualization can help figure out a future that is much more exciting.

Another year has come and gone, and many exciting things have happened in information visualization. Here is a look back at some interesting events from last year, as well as what I expect for 2012 and the next few years. [Read more…] about The State of Information Visualization, 2012
I am spending the entire year 2012 in Seattle, working with Tableau Software. The topics I will be working on include storytelling and Tableau Public, plus some super-secret projects even I don’t know yet (mostly because we haven’t decided on them).

For more than five years, the ZIPScribble Map and its related pages have been the most popular feature on my website. To freshen things up a bit, I am adding an interactive version that runs in your browser. I have also added a few more countries, for a new total of 38.

As we’re heading towards elections again, there is a chart type that is as unavoidable as political ads, baby-kissing, and smear campaigns: line charts showing polling data. The most common pitch two candidates against each other, and often make a big deal out of the fact that the lines cross.

In my enthusiasm about switching to WordPress, I made the mistake of tweeting about potentially increasing my posting frequency in 2012. While I have tried to stick to a roughly weekly schedule in the past, there have been weeks when I did not write anything. My hope is to increase the frequency to roughly twice a week and see how that goes. John Peltier and Jorge Camoes are planning on doing the same. [Read more…] about New Posting Frequency for 2012
I was asked to write a review of two recent visualization books for Science: Nathan Yau’s Visualize This and Manuel Lima’s Visual Complexity. The piece appeared in the last issue of 2011, right before Christmas. Below is a link to the review and some additional comments on it and the two books.

After more than five years, switching the content management system (CMS) on eagereyes was not an easy decision. I’ve been thinking about doing that for a while though, and I want to explain my reasons and what I expect WordPress to do better than Drupal below. This should also be useful for anybody who is on the fence about starting a blog (or has a blog that hasn’t been updated in a while).
