Strangers in Paris: census maps, layering, and data compression

April 20, 2011 by


I have been working on a blog series on census data visualizations for another site (which will be reproduced here when it’s all up). First of all, I am using that as an excuse to justify how little I have been posting in the last couple of weeks. However, there is also something I could […]

Visualizing a Public Good

March 25, 2011 by


Have you ever been waiting for a bus for half an hour, only for two half-filled buses of the same route to roll up to your stop?

Created in the 1890’s by Irish Captain Matthew Henry Phineas Riall Sankey to demonstrate the efficiency of steam engines, it was popularized during Napoleon’s Russian campaign as an efficient way […]

The superbowl, earthquakes, and spatial statistics

February 4, 2011 by


In anticipation of Superbowl weekend, I figured I should post a football-themed data visualization. Now, I was thinking about doing something on one of the playing teams, but my best friends are split down the middle between born-and-raised Wisconsinites (including Dan Plechaty, one of our contributors) and Pittsburgh natives. So I decided to display this […]
