"CyberGeography is the study of the spatial nature of computer communications networks, particularly the Internet, the World-Wide Web and other electronic 'places' that exist behind our computer screens, popularly referred to as cyberspace." The Atlas of Cyberspaces highlights many efforts from around the world to visualize this type of information. Some of the features have links to download software tools, like an experimental browser that portrays Web sites as three dimensional buildings (the bigger the building, the more popular it is). Other features are more abstract; one project at Harvard University developed a visualization tool that depicts users' online behavior.
