A Very Distorted Cartogram Map

NPR Maps Election Spending

A cartogram map scales geography proportionately according to some value of interest. Usually cartograms maintain the shape and relative position of the basic map as much as possible.

Maintaining a recognizable map of the US was a problem for this cartogram because political spending is so heavily concentrated in just a few states. This shrunk all the other states to the point of becoming almost invisible and certainly made them unrecognizable.

NPR’s solution was to turn the cartogram into an animation. Starting with an undistorted US map, NPR then morphed the US to show the highly distorted spending picture shown here.
