The WikiViz challenge has now been officially announced. The challenge is to create the most insightful visualization of Wikipedia’s impact
“The main goal of this competition is to improve our understanding of how Wikipedia is affecting the world beyond the scope of its own community.”
There are more details here.Any inspirations? One of the organizers is Dario Taraborelli from the Wikimedia Foundation (he is one of guys behind the not necessarily useful but ridiculously aesthetic Wikipedia deletion discussion visualization). He has made the Readermeter Mendeley readership analysis and visualization website. So maybe you could do something similar with the Wikipedia reader statistics at http://stats.grok.se/ or the raw data here? hmmm… It may be a good idea to take a look at the First Monday article Visualizing the overlap between the 100 most visited pages on Wikipedia for September 2006 to January 2007.
