Oh Raphael has moved on significantly since June.
There is a new charting library that can work with it and these are very eye catching.
Raphael also supports full SVG path syntax and is incorporating really advanced path methods. Come see 1.2.8+ at my site (Shameless plug) and then bounce over to the Dmitry's site from there.
