Based on Mike Bostock’s [World Map][0], modified to automatically colour countries such that no adjacent countries share the same colour.

This is done by extracting the topology via [TopoJSON][1] and greedily picking colours until the constraint is fulfilled.

See also: [Graph coloring][2] on Wikipedia.

Update: Greedily colouring is now performed in a single line, thanks to Mike Bostock!
