Connections created when users reply, mention or follow one another. The data set starts on 2/22/2012 14:54 and ends on 2/28/2012 5:20 UTC. Green lines are "follows" relationships, blue lines are "reply" or "mentions" relationships.Layout created with the "Group Layout" feature of NodeXL which tiles bounded regions for each cluster. The Harel-Koren layout algorithm positioned each vertex: en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing). Clusters calculated by the Clauset-Newman-Moore algorithm are also encoded by color.
