Dear Marc,

maybe you can use RGL in some way:

http://rgl.rubyforge.org/rgl/index.html

There is some care taken of the distance in the second example module_graph.jpg, 
not yet what you asked for, but there's a description language, 'dot', associated to the
project,  which might be tweakable into what you asked for.

Best regards,

Axel
