I've got a few ideas to improve the Rank Evolution charts, using a Google Finance stock chart as inspiration. Some of them might be hard to implement without using Flash (as Google does), but think some of these ideas would be really fun. Especially rescaling the charts by number of games played and adding new trophies like "Most Victories in 1st Place" or "Longest Time in Top 20" (measured by # of games) would add more dynamism to the ranking scoreboard without having to resort to ELO erosion for inactivity.
