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).

Note: It is possible for users to have the wrong icon rendered in the static image. Github for example allows users to change usernames and the data is from 2012. The icon in the overlay is what is current now on the website.
