More cartograms: Population, GDP, & more

Mark Newman (see previous post Another world population map) has used his cartogram technique to make a series of sharp cartograms of the world (smoother than these rougher cartograms), some of which are shown below (land area, population, GDP, and GHG emissions):
Map of world

Population Cartogram

GDP

GHG emissions

This approach was used to create the simpler Worldmapper Project collection of cartograms. A series of their population cartograms are showed below.

Land AreaMap by land area

Pop 19001900

Population 19601960

Population 20002000

Population 2050 - estimated2050 (UN med. projection)

Information and code for the cartogram algorithm are available on Michael Gastner’s website.
