I like this tool quite a bit especially the parts where it takes text files of nodes and edges and creates diagrams of various types - a la Graphviz.
I wonder if there's a forum somewhere to discuss how to use it (and when.) I am one of the many who gave up Stack* for all the reasons. For example, it can ingest and excrete Visio formats with varying degrees of success. I'd like to understand those limits for when I need to work with people who have Visio.
