New, Improved Traveling Presidential Candidate Map
Many years ago, when this website was still young, I created a map of all the ZIP codes in the U.S. in numeric order and then wondered about the shortest path through all of them.

The Café Wall Illusion in a Bar Chart
The Café Wall Illusion makes you to see perfectly parallel lines as being at an angle. It’s a curiosity and a cool perceptual illusion – except when it shows up in a bar chart, as it did in this example. Continue reading The Café Wall Illusion in a Bar Chart

A Pair of Pie Chart Papers
How do we read pie charts? Do they differ from the even more reviled donut charts? What about common pie chart designs like exploded pies? In two papers to be presented at EuroVis next week, Drew Skau and I show that the common wisdom about how we read these charts (by angle) is almost certainly wrong, and that things are much more complicated than we thought.
