Thanks, I've dug out the paper. It's very interesting. You are trying to
solve a slightly different problem to the one I had in mind (the focus
on handling extremely large data sets), but it's definitely along
similar lines. I haven't absorbed it all yet and will read on.

We've been working on this approach at Leeds. Last year we submitted an
entry to the IEEE Visualization contest using a rendering framework
where you create something akin to a scene graph as a data structure.
Interfacing with OpenGL is done behind the scenes, including traversing
the tree to render, and to respond to events. See our paper in PADL'09
- source code at www.comp.leeds.ac.uk/funvis/.
We're currently extending this in two directions. One is better support
for writing embedded interactors, which transform a tree in response to
an event. We now have a nice parallel coordinates example with
interactive brushing of the axes embedded directly into the scene, hope
to put up on the web at some point. The other ...

... is essentially that, though for vis pipelines rather than just
graphics. Not yet at a point where we could answer Conal's questions,
but also working towards it.
