Sure you could use longdesc for that. Or you could embed SVG directly - it
can be done to transform reasonably nicely and include a link to the image
for a browser only capable of handling it via a plugin/helper, like IE and
Lynx.

It is an open issue I think whether it is good to use longdesc for something
that isn't HTML as a tatrget.

There has already been work done on this - RDFViz, the  text-only SVG browser
written last year, etc.

  that image, it would be a help. I thought of this as I was preparing to
  draw yet another node and arc diagram for EARL, and realised how difficult

  be brilliant. Could you use longdesc for that, and then embed the SVG into
  the longdesc page?
