I was wondering if it is possible to include SVG content inside a panel (or whatever would work in GWT), be able to add more to the SVG (like add a circle or a curve) programmat
We just open-sourced a GWT widget that allows you to integrate GWT with Raphael: http://code.google.com/p/raphaelgwt/
This widget was originally created for Hydro4GE and was mentioned in an article on the official GWT Blog.
