Visual Tree (graph) generating

I'm trying to find a piece of softwa开发者_如何学JAVAre or some API / technology that would allow me to do the following....

I'm looking to generate a family tree based on input I was to feed into a piece of software. I'd like each child of the tree to be clickable and for me to embed it into a website somehow.

I think AT&T's graphviz is a great tool for displaying trees.

This link suggests that it's possible to associate a URL with a node: "...Note that URL tags are respected, to allow clickable PDF objects..."

Have a look at Ryan Schmidt's Canviz parser for Graphviz output. It takes the xdot output you'd get from running Graphviz on a server and renders it using pure Javascript.
