I’m looking for a Javascript library/engine that can do graph layouts. (And when I say layouts, I mean logically position vertices nicely.) The graphs I’m working with are all m-ary trees. M is usually no more than 5 or 6, but it can be greater in some cases.
I do have something that I use now, Graphviz’s node program, and it works perfectly. The problem is, when running a web app, I have to send a request to the server every time I want a layout. Preferably, I would like something written in Javascript that can be quickly run on the client side. All it needs to do is provide layout information (relative positioning and whatnot). I don’t need it to draw to a canvas or use SVG or anything, all I’m interested in is the layout.
Library use like jQuery or RaphaelJS is fine by me. I’ll work with it. I’m just looking for something to speed things along a little.
Also, I’d consider writing my own if I could find a nice description of an algorithm to do the layouts. But I really don’t want to spend too much time. I have something that works now, so getting it on the client side is just a bonus, not a necessity.
Take a look at D3 (Data-Driven Documents)

They have some beautiful graph layouts.
