Yes, thanks for putting your thoughts into words. When I first saw this I just "felt" it was pretty cool, but couldn't really explain why.
As a numbers geek one of my pet peeves is that people all too rarely play out different scenarios to help the reader gain an understanding of the underlying model/data/relationships/etc.
Now some sites do this well (e.g. OKCupid's blog), but there is still a disconnect between text and data display. The reader has to play with the graph itself and that does create a bit of a cognitive fracture that I think subtly inhibits a better understanding.
