Anthony, I was looking for the same thing and ended up rendering my svg paths and attribute data as json then using the Raphael JavaScript Library to render the data on screen. That library is really nice; it has some very handy functions for interacting with SVG path elements, which also can be handled by jquery $(element). It also does svg transforms and matrices in the 2.0 version which really helps when you are trying to draw geographic coordinate based stuff.
