Pretty darn interesting. Both up close and zoomed all of the way out. Let's just say that Spinal Tap would like this chart.

I, of course, would rather see it trend all sequels, reboots, etc.. and not just the original and first sequel. But I realize they would need a new method of infograph to do that.

Also, I think they should have used red/blue and shades of purple to represent the financial deltas between the sequels, as oposed to just the size of the bubble to represent box office of the sequel.

The site has a lot of other cool graphs too.
