view xml-schema with svg

Hi,

I was looking for an possibility to view the xml I described with 
xml-schema. So I found the xsbrowser, but it hasn't satisfied me.
The Problem is, you can't see the whole structure.You always have to 
click on link and you only see the current element and its attributs and 
subelements.

First of all I'd like to ask if there're any other tools (for free), 
that shows me whole structe, for instance as an image.

I also had the idea to develope a tool that generates a svg file with 
the structure, but I'm not sure if SVG is the right format. Is there 
anything similar in progress?

Many thanks in advance.
