I'm gonna have to disagree with you here... This is beautiful, and much richer than the NYTimes version because it depicts not only total sales, but box office position. Tufte would be proud...
I wish that was the only thing it was missing! If I did this in, say, Flash or SVG from the start, I think I could make many more things visible on mouseover. The PNG tools are the closest at hand, though.
I also wish it was easy to search for a particular movie. I wanted to show a friend the interesting path of Little Miss Sunshine, but it took me a while and some mousing to find it again.
It's pretty decent for aimless browsing around for interesting patterns, though.
