Re: HowTo GraphViz?
Hi ronny, and welcome to Tiki Community!
I've had a go to graphviz, since I remembered from years ago that it looked a useful application to visualize graphs, etc. And I managed to make it work with plugin wkigraph (in mods) with Tiki 3 LTS (but not with the current trunk, the future 6 LTS):

I have no idea about the syntax needed to work (I'm newbie in graphviz)
