Chris Harrison created this interesting map of the world's Internet Map, a connection density that visually depicts the structure of the web (by router configuration):
The first rendering displays the relative densities of Internet connectivity across the globe. The stronger the contrast, the more connectivity there is. It is immediately obvious, for example, that North America and Europe are considerably more connected than Africa or South America. However, it is important to note that this only reflect density of connections, and not usage. Hundreds of people may utilize a single connection in an internet cafe, often the only form of connectivity people have access to in developing nations.
