I suggest if you want to do wire-frame drawing, stick with Java, or perhaps Flash.
if your primary concern is to draw lines and shapes and you are only using IE5+ then you may be in luck.
MS has a patented technology known as
VML(Vector Markup Language).
It helps you draw lines and shapes pretty easily.
Look into that...
Khalid Ali - Thanks for that, I knew Microsoft would have put something in there to make it harder for any other browser to compete; sorry I mean to make life easier for the likes of me.
Thanks, your feedback is all useful; saving me time and pointing me in the right direction.
