Graph visualization code in javascript?

I have to integrate a graph with nodes and edges on a web page. Ideally, i would like to be able to interact with it (like moving the nodes around).

Actually, i'm beginning by representing trees, so i would appreciate to be able to collapse subtrees.

How can I do that ? I was considering google-visualization api but i wasn't able to find the kind of visualization i'm looking for (org chart doesn't allow to have multiple fathers, if i understood well)

I've got no idea of the kind of technology so my tagging may not be really accurate :-).

thanks

Two other options are:

• Prefuse Flare which is in flash
• JavaScript InfoVis Toolkit (JIT)

RaphaelJS may be of interest to you. Particularly this example.

http://processingjs.org/ might have what you're looking for.

I'd go for SVG (all 'newer' browsers implement it more or less; older via plugins: e.g. IE6).

If you want to make it interactive javascript manipulation should be doable.
