Project Description:
Vizster is an interactive visualization tool for online social networks, allowing exploration of the community structure of social networking services such as,, and orkut. Such services provide means by which users can publicly articulate their mutual "friendship" in the form of friendship links, forming an undirected graph in which users are the nodes and friendship links are the edges. These services also allow users to describe themselves in a profile, including attributes such as age, marital status, sexual orientation, and various interests.

Vizster provides a visualization of such services, providing an interactive sociogram for exploring the links between network members. In addition to visualizing "friendship" linkages, Vizster supports a range of exploratory search features, providing visualization of the rich profile data characteristic of these services, features which traditional sociograms are not designed to communicate.
