Internet Maps

The DIMES Project (now defunct) provided several excellent data sets that described the structure of the Internet. Using their data, I created a set of visualizations that show how cities across the globe are interconnected (by router configuration and not physical backbone). In total, there are 89,344 connections.

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 reflects density of connections, and not usage - many people may utilize a single connection in e.g., an internet cafe.

I also created three graphics that display how the net is connected. I should note this is not the first time graphs like this have been created - I've seen several variations, most being practical in nature (undersea cables, bandwidth, etc.). I decided to pursue a more aesthetic approach - more visually intriguing and interesting to explore than useful. The intensity of edge contrast reflects the number of connections between two points. No country borders or geographic features are shown - the only thing plotted is data. However, it should be fairly easy to orient yourself.

Note: These visualizations use a cylindrical equidistant projection. This means that the planetary surface area represented by each point varies, skewing density data (both points and edges)!

High resolution bitmap versions have been provided for detailed examination or print purposes. If you do decide to print, please let me know. I'd love to see a photograph of it in your home or office. Email me if you want a vector version.
