   Re: [xml-dev] Graph markup

[ Lists Home | Date Index | Thread Index ]

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.
