GraphViz and SKOS...

Hi!

I always resisted graphing thesauri relations because I thought 
relations can be presented through adequate layout and typography.
I found by accident GraphViz ( http://www.graphviz.org ), an open source 
software existing since 1996 doing exactly what a non-graphic designer 
dreams:
draw a good schema from logical relations...

Many examples are in the documentation:
http://www.graphviz.org/pdf/dotguide.pdf

May be some of you know a better or more recent tool? Please let me know!
The interesting thing to do now is to translate automatically and SKOS 
file (or extract) into a .DOT file...
     Anyone has done experiments in that direction? Can we learn about it?

My opinion is that drawing rapidly and effortlessly schemas based on 
EXTRACT from a thesaurus is very valuable for discussions between 
validators.
I would like to integrate .DOT generation into ASKOSI.org.

Have a very nice day!

Christophe

P.S. I invite you to test the following (written in .DOT graph 
description language) using some of the available Web services (for 
instance: http://graphviz-dev.appspot.com/).
It is an example of a thesaurus extract under revision:
