Infographic: Global Internet Map 2012

From TeleGeography, a map showing Internet connections (and capacity) among the countries of the world.

(There's also an interactive version where you can zoom in to look at various areas)

It may be a bit of a surprise initially, but they show International Bandwidth Growth rates slowing (falling to around 40% annual growth rate for the last year).  But that's partially the result of the fact that a lot of the basic international infrastructure has already been established, combined with the utilization of already-installed dark fiber.  (Fiber optic cables are installed in bundles - those that aren't immediately used for traffic are called "dark fiber" and are held in reserve to handle traffic as demand and utilization grow.  Thus growth doesn't necessarily require rebuilding whole networks).

They also show that despite the huge increases in traffic and network expansion, the prices for IP Transit Service (moving data across networks) continues to fall.
