So far, all of the examples I have encountered are "text-centric".
E.g., programmatically searching/replacing/inserting/etc. text
based on actions/input from the user.  "Smart *Forms*".  Similar
to the "order form" example I mentioned previously.

But, I haven't been able to find anything that addresses creating
*graphic* content, on-the-fly.

E.g., I can play a canned audio snippet.  Or, an animation/movie.
But, I can't "draw an X" (or, a tic-tac-toe board) with any sort
of JS commands I've seen, so far.

I'll have to keep digging.  I can't believe they would overlook
such a useful feature...
