Drawing lines, pixels, circles with DHTML/Ajax/ActiveX

Hello,
I am writing a no-plugin networked Sketchpad program (DHTML,
Comet/Ajax). Because I am trying to avoid using Flash or Java Applet, I
rendered my strokes at first with the wz_jsgraphics library
(http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm). It turned out
that that was too inefficient, and if you drew too many things on the
screen firefox would crash. So I looked into SVG for Firefox. This
works great because it is rendering a vector drawing (instead of many
absolutely positioned div elements). The problem is that IE doesn't
support SVGs.

My question:
Is there something I can use with IE that can draw
lines/pixels/circles/etc. without needing plugins? Any ActiveX stuff I
can do? My goal is to check if the browser supports SVG. If it doesn't,
it will render with Active X, or whatever solution there is for IE.
Anyone know of anything I can look into?

Thanks,
Jason Ho
