I love how the death star article is on there. Though I don't know that this qualifies as an infographic: the only info on it is title + num_edits. The relative sizes aren't informative, their locations aren't informative (horizontal or vertical, I'm sure the Jesus article is still highly edited).

http://en.wikipedia.org/wiki/Wikipedia:Lamest_edit_wars for the data. Not sure where to get the edit counts, aside from checking the history statistics.
