Great post. I've used it to generate UML diagrams from databases with sqlalchemy, and more recently to generate protobuf diagrams in Python (needed it quickly to update some documentation): https://github.com/kinow/protobuf-uml-diagram https://github.com/kinow/protobuf-uml-diagram One thing that I think was not mentioned in the article, are invisible nodes, which are really handy: https://stackoverflow.com/search?q=invisible+node+%5Bgraphviz%5D https://stackoverflow.com/search?q=invisible+node+%5Bgraphvi... Some times the existing layouts, ranks, clusters, etc, won't help you to produce the diagram you have in your mind. So instead of giving up and drawing it in draw.io or Inkspace (which I used to do), a co-worker showed me how he was using this technique in several of his diagrams.
