graphic tools?

I have a set of xml files. One file contains references to other files and other files contain references to yet other files.

Is there a tool out there that when given an xml file, figures out the dependencies and displays the relationships in a graphical way?

Thanks!

You write some simple software to do it yourself. As explained in another thread, investigate SVG (Scalable Vector Graphics). This is a graphic file whose source is only XML. So you can write a class to pull certain links to other XML files as you say and place them into another XML (the SVG). This can then be rendered by a web browser with a SVG plugin.
