Pyjamas is a stand-alone python to javascript compiler, an ajax framework / library and a desktop-like widget set.

this package contains a port of the gwt canvas library, to pyjamas. written in pure python, it can be used to create scalable vector graphics applications in either a user's web browser (compiled to javascript), or as a desktop application under pyjamas-desktop.

an online demo is here: http://pyjs.org/examples/gwtcanvas/output/gwtcanvasdemo.html

please note: pyjamas-canvas is experimental but functional, and does not yet provide vml support (used exclusively by ie). pyjamas-desktop (with the xulrunner backend), firefox and google chrome have been confirmed as working.
