There is Milslav Nic's Graphotron at the www.xvon.org/ site. It is amazingly terse: unlike the pic-in-xml graph languages it is a specialist transformatin tool. It lets you have your instance data in vanilla XML (i.e. not specified in terms of nodes or arcs); you specify a transformation using XPaths into arcs and nodes. Probably the way of the future. I haven't tried the implementation, so I don't know how sophisticated it is doing complex layouts.
