[thelist] DHTML Zoom / Pan / Palette

I have the end goal of an application that will create an interactive graph 
or tree. Once the nodes are drawn on the page I would like to allow the user 
to Zoom and Pan around to investigate the various nodes in the graph/tree. 
Much like Google Maps.

What I was wondering is if there is some standard technique for implementing 
Zoom/Pan via DHTML. Is there some Library or Framework that would speed this 

Lastly, when drawing square nodes does it make sense to use absolutely 
positioned DIVs with their border's set to 1px? I'm sure using an image 
would be more attractive, but I think DIVs would be more efficient if a lot 
of nodes were to be displayed. I'm also thinking that relative positioning 
wouldn't make sense for this application. Am I right?
