why you want to draw it without bitmaps?

I think it makes full sense, in many cases. Don't you think sending bitmaps on each request is somewhat wasteful? Vector graphics and client-side processing (in Web applications, powerful client-side machines are always under-used) can be much better.

I up-voted this question with my 5 and answered it, please see my solution.

Without bitmaps? You can use HTML5 vector-graphics canvas feature:
http://en.wikipedia.org/wiki/HTML5[^],
http://en.wikipedia.org/wiki/HTML5_canvas[^].

You can learn it using, for example, these tutorials:
https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Canvas_tutorial[^],
http://www.html5canvastutorials.com/[^].
