About

Ekisto is an interactive visualization of three online communities: StackOverflow, Github and Friendfeed. Ekisto tries to imagine and map our online habitats using graph algorithms and the city as a metaphor. Ekisto comes from ekistics, the science of human settlements.

A graph layout algorithm arranges users in 2D space based on their similarity. Cosine similarity is computed based on the tags of posts contributed by users (StackOverflow), collaborate, belong, watch, fork and follow relationships (Github), or based on the followers/following links between users and groups (Friendfeed). The volume of each user represents the normalized value of the user's Pagerank (Github, Friendfeed) or their reputation points (StackOverflow).
