Hey, so why trying introduce a colleague of mine to Frappe he had issues comprehending the concept mostly as a result of not being able to visualize the various doctypes. So, I thought to do something about it an wrote a python script to do just that using PlantUML.
Above, is the output for the Frappe tutorials on a library management app. I just thought I should put it here in case anyone ever needs it, clone the repo here or install via pip and use in you terminal or as a module to try it out.
