The following map shows various countries of the world such that they are
shrunk or grown based on some sort of relative statistics.

I want to generate these maps for the 50 US states using my own
statistics.

First, I need to know what these maps are called. I can't search for them
without knowing what they are called.

Second, I need to know how to generate them myself.

Uclue Researcher Answer by Researcher pinkfreud on Tue 18 Nov 2008 - 7:00 pm UTC:

A proportional map as shown on your linked site is called a cartogram.

"A cartogram is a map in which some thematic mapping variable – such as
travel time or Gross National Product – is substituted for land area. The
geometry or space of the map is distorted in order to convey the
information of this alternate variable."

Here you'll find two cartogram generators:

Mapresso

Frank Hardisty's Cartogram Generator

I hope this helps!
