I've just thrown together the gutts of the player ranking graphing pages. Currently you can choose a level set and time period but not the players (they are hard coded off one of the top tens but do add the currently logged in player). Here's the first cut. Feedback and suggestions welcome but I'm keen to get other pages out so nothing too complicated. This first image shows the opening month of the Tropical level set.

Note that this link will go tot he current time from two weeks from this posting.
