I saw an even kewler visualization a couple years ago
(alas, I can't recall the link). It generated a little "Sim" city
type animation of website traffic, with the major pages being
tall buildings, and the number of visitors represented as pedestrians,
taxis, or buses, visiting each page/building. Not sure just how
useful it was, but it was serious eye candy. (sure wish I could find that URL...
And it was all animated so you could see the traffic flow as visitors moved from one page to the next.
Found it! Visitorville
