Worldmapper

Have a look at the maps of http://www.worldmapper.org.

Unlike conventional maps where a country's size is representative of the amount of land it owns, the size of countries on a cartogram are scaled according to a certain factor.

E.g. the countries on this map are scaled by nuke ownership: http://www.worldmapper.org/images/largepng/289.png

Scaled by metal export:
