From Moritz Stefaner on Visualizing.org, comes the VIZoSPHERE project (Click the image to see the high-resolution image viewer). Using GePhi, Moritz started with 18 seed accounts on Twitter, and then mapped 1,645 of the connected, networked accounts that relate to data visualization. Bubble size in this visualization shows how many followers each account has from within this DataViz pool of users.
This map shows 1645 twitter accounts related to the topic of information visualization. The accounts were determined as follows: For a subjective selection of “seed accounts”, the twitter API was queried for followers and friends. In order to be included into the map, a user account needed to have at least 5 links (i.e. follow or being followed) to one of these accounts. The size of the network nodes indicates the number of followers within this network.
 The seed accounts were; @moritz_stefaner, @datavis, @infosthetics, @wiederkehr, @FILWD, @janwillemtulp, @visualisingdata, @jcukier, @mccandelish, @flowingdata, @mslima, @blprnt, @pitchinteractiv, @bestiario140, @eagereyes, @feltron, @stamen, @thewhyaxis
The zooming interface is crucial to view such a highly-detailed visualization and be able to read any of the nodes. I was about to find my own Twitter account (@rtkrum), but it would be nice if Moritz would also provide a listing of the Twitter accounts or some way to search the map.
Great job Moritz!
