Well, svg on IE requires a plugin while the canvas element seems to be
support by all major rendering engines. So why make things
complicated? Anything requiring a plugin leads to usability problems,
i.e. I don't have to point out the endless jmol is broken with gcj
issue we have to deal with. A solution that just works, but isn't as
pretty as one that requires plugins is still preferable.
