Allow SVG graphics to overflow outside the containing svg element

I'm using the Raphaël—JavaScript Library to create some pie chart graphics, but I want to set the overflow of the containing SVG element to visible, to allow the graphics inside to display outside of their开发者_如何学Go container. The way you would with normal dom elements (overflow: visible;) does not seem to work for svg containers. Does anyone have any experience of this or know how to remedy it?

Cheers

It's a bug in Firefox.

WebKit implements overflow: visible correctly for SVG elements, as does IE for VML elements.
