Cartogram

A cartogram is a diagram or a distorted visual representation of the area of land. The values are what create the distortion within the areas within the mapped region.

The example map shows the distortion within the Unites States of the constituents of the House of Representatives of forty-eight states (excluding Hawaii, Alaska and U.S. territories).
