I found an interesting post on Reason magazine's Hit & Run blog in which the Gross Domestic Products (GDPs) of various nations are correlated with the GDPs of US states. The map is a fascinating comment on global economics, and more info on its background is available through the original Hit & Run post.

The Hit & Run blog, incidentally, is a product of the libertarian publication Reason, which, regardless of what you think of its politics, is a good place to troll for stories pertaining to visual culture.
