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.
