I still can't really interpret them easily though even after looking at them on separate occasions, they still don't make any sense to me without really thinking.<p>I guess I'd rather see a line graph for each in a different colour with time on the x-axis - as it is I can't get it in my head which column is which, and it's really hard to get a feeling for how they change in relationship to each other over time.<p>Also, they aren't really that HTML5y, they are made up from a sprite sheet: <a href="http://www.googlezeitgeist.com/img/graphs/toplists/spritesheet.png" rel="nofollow">http://www.googlezeitgeist.com/img/graphs/toplists/spriteshe...</a>, so aren't being rendered using CSS transforms, canvas or SVG. Also, the developer hasn't rounded things properly, so you get things like heights being set as 147.75700934579436px. It's not exactly a problem, but this could have been handled in the JS.<p>Other than that though, they do look nice.
