I have started doing a code review for someone, and there is a large inheritance model (many layers deep). After filling up my white board, I realized that I need a tool to draw this out.
What is the best tool (preferably free) to draw this out, so I can visualize what's happening in the code base. The code is in Python, but I think my question or the solution should be generic. I don't mind drawing it out by hand as the value for me is the scalability around the visualization.
