I had tried GraphViz in the past and couldn't get it to work. I installed the Windows binary from GraphViz's site then installed the Ruby module. Running the samples output (what appears to be) byte data which I redirect to a file with the extension 'png'. When I try to view the output, nothing renders it. Excluding that, I was hoping to find something more in-line with http://zedgraph.org/wiki/index.php?title=Main_Page (only for Ruby instead of C#). -Dave -----Original Message----- From: Alexandru E.

Hi, I think GraphViz is what you're looking for ;) the tool: http://www.graphviz.org/ the ruby module: http://raa.ruby-lang.org/project/ruby-graphviz/ <disclaimer> never used the ruby module yet, as I am pretty new to Ruby (< 30 days). </disclaimer> I have used GraphViz however, and is a really cool piece of software :) check out the gallery: http://www.graphviz.org/Gallery.php Good luck, Alex
