OTOH doing this via DHTML is kinda unpractical and may be done as an exercise if one has really really a lot of spare time to spend. IMHO zooming / panning a vector-based node-tree requires an app that understand vectors. Flash could be a good candidate in this particular situation. Though depending on the complexity of your project requirements it can be done with DHTML. And there are excellent 2D / 3D DHTML models &libraries around.
