You might as well just use something like plantUML instead of this from a productivity standpoint. However, I don't want to discount the value of Graphviz. Python has a little known class diagram generator built into pylint which uses Graphviz for its rendering and its pretty cool. You can find out just how bad your #BIGCORPS code architecture is just by checking a reasonably large project with Pylints class diagraming tool...
