Knud, Kingsley:

Thank you for the hints. Since OmniGraffle is restricted to the Mac environment, I used yED Graph Editor (http://www.yworks.com) which works with graphml. So I can use a template to produce the nodes and edges, and the (organic, hierarchical etc.) layout tools of yED to build a layout to a large extent automatically.

In case somebody feels the same needs, I post the template here.

Cheers, Joachim
