Hi,
Using Wikipedia's API I developed a web-based tool to plot revision
activity timelines for Wikipedia articles.
See the revision activity for "Tour de France":

Also check the Greasemonkey script that embeds these timelines in
Wikipedia using Google Charts:

Feedback is welcomed. Thanks!
PS: Btw, I would really appreciate if you could vote on this bug :)
