Dan Lynch ported some of pstricks to js[1], which you might be interested in checking out. Don't know if you can do intersections and cuts though...

Hm, that is a nice start indeed, but as far as I can tell, intersections and cuts are not in :(. pstricks I forgot, I know that as well.

I am not that attached to the syntax, just the possibilities and some of the vocabulary.
