US Election Cartogram
November 7th, 2008Today I’m not doing a redrawing; I don’t need to. The magnificent Mark Newman, one of the authors of The Atlas of the Real World has done it for me.

Finally, let’s scale each county by its population, to show the distribution of votes to human scale:

Lovely!
Further - we can now compare a cartogram produced on the same principles for the 2004 election:
