Yeah I could create something like that. This sort of analysis was done in the
Road to 1,000 (Plays) article and I was planning to make a new one now that we've passed 7,500 plays.
I also was considering just making many of those special graphs "live". I've got a new charting plug-in that looks promising.
If there are other queries you'd be interested in seeing feel free to list them in this thread and I'll add them to my own plan provided they're workable.
