Hi Ulrich,

I was unable to determine where graphviz would be installed on darwin. I have added cases in the j addon for Windows, Ubuntu and Centos.

Do you have the graphviz darwin package installed? If so, can you tell me the path to the standard sample graph files? If I get the path, I can add it to the addon.

Thanks,
David Mitchell
