Starting in the late summer we will implement a much less hackish API
for doing this type of thing.  That new API will some quite different
than what you are doing now.  Your current approach may continue to
work, but might need some changes.  The more you do now, the more you
will have to change.  The less you do now, the easier it will be in
the future.  The other thing that I mentioned on the sympy list is
that once the better APIs are in place, there are going to be
*multiple* libraries that emerge for doing d3 based plotting in the
notebook.  If you just wait, you can use those libraries without
inventing your own.  If it were me, I would wait and work on other
things in the meantime.

Cheers,

Brian
