I've been thinking of doing something like this for awhile: render my web statistics in on-the-fly SVG graphs via some XSLT. Rob did something like this way back when he first started his blog. I know Mint has the powerful "Fresh View" pepper that uses SVG to display its data visually. Andrew Gregory has had his home-brewed solution for a little while now. But this one just came up in Technorati, it includes the 3 small files you need to tweak. Fun "milk carton" WordPress template, too.
very nice post!!
