Cartograms

issrweb.asu.edu/services/gis/sample-maps.html

Cartograms are maps where the geographic unit being looked at has its size and shape altered to reflect the magnitude of the variable being looked at. Algorithms which create cartograms are designed to maintain the approximate scale and positions of the original geographic units as best as possible given the necessary distortions. The Cartogram map above shows county populations for the area of the United States.
