I'm using raphael for a visualization project and it works great. The big advantage over canvas is really more significant when your drawings need to be interactive since you can tie event handlers to graphic objects. The problems with it are more related to the cross platform nature like the radial gradients in the article. Also translucent shapes don't seem to be transparent in IE. Another thing that I am missing out on is having some kind of scene graph. Raphael has groups of objects but it is a far cry from what you get in SVG.
