Data set: nodexlgraphgallery.org/Pages/Graph.aspx?graphID=415

 

These are the connections among the Twitter users who recently tweeted the word pda12 OR pda2012 when queried on February 23, 2012, scaled by numbers of followers (with outliers thresholded). Connections created when users reply, mention or follow one another.

 

The data set starts on 2/17/2012 0:05 and ends on 2/24/2012 0:06 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. Clauset-Newman-Moore algorithm is defined here: pre.aps.org/abstract/PRE/v70/i6/e066111
