Flow maps

http://www.worldchanging.com/local/canada/archives/011736.html

Flow maps show the movement of object's or information from one area to another.  This map shows an example of trade between 28 countries. The size of the bubble indicates how much trade is executed. The lines in between each bubble show where the trade is going. The color of the bubbles and routs shows the regional memberships where they belong, such as the EU and EFTA.
