Purple America

Robert J. Vanderbei at Princeton takes the red state / blue state meme to a much more informative level, using shades of purple on a county-by-county map to show the results of this election.

On another map, he even added false mountains to designate areas with higher population.

What a great way to clearly convey a mountain of complex information. Edwin Tufte would be proud.

UPDATE: An apparent Tufte fan found a map of Purple America with highly-populated areas artificially expanded. Groovy.
UPDATE 2: More maps.
UPDATE 3: Another one using elevation for population differences between counties (I’m guessing it’s showing population density, not absolute population), and no shades of purple.
