A cartogram is responsible for presenting some form of statistical data in a geographical distribution on a map.  In doing so how ever many times it is in a simplified and abstracted form, usually on a distorted map base.  Above is a perfect example because those are not the exact shapes of the states, and in a way they are estimated and shapes are made simpler form wise than they are in actuality.
