Please don’t be afraid to USE LABELS on your charts 🙂 
Nice smooth transitions. Maybe use less white-text-on-light-colors!

I like the way the transitions between datapoints work. Very smooth.

Ooh. This graph is pretty. Nice color scheme. -MH

I agree except the head color and font color are so close.
– I think that’s because of the projector -MH
– yeah that is possible

White on cyan isn’t very visible. Sorry, this projector is ASS. It looks much better on his laptop 🙁
    How about the white on yellow?

I was a little bit confused initially because it looks like there is an x-axis but there really isn’t (it’s just categories). Wonder if there’s a way to make that more clear. I wonder if it’s even necessary to have them displayed in a line like this. If you just randomly placed the bubbles around the screen I almost feel like you could still get the point because the size of the bubbles is really all that matters, right?

I like the mouseover interactive-ness.  Very, very cool–I espeically like how if you click on a particlar part of the data set another data set comes up with more information.  Maybe includes some numbers or labels on the axes?  May look a little cleaner.  I’m not exactly sure what information is going along each axis.  Also, maybe this isn’t true when you click on the cirlces, but I’m wondering if you need the y-axis, since the cirlces seem to be aligned on the horizontal axis.  I’m not quite sure though…since I’m still not exactly sure how you’re expressing your data though. Nice job though… 😀 -Amanda
