The SchemDraw package, developed by Colling J. Delker, allows for the creation of high-quality electrical circuit schematic diagrams. Create a python virtualenv with pylint installed. In a good number of the diagrams I have created in the past this was not always necessary, but as your architecture grows grouping these nodes within clusters usually enhances readability. I was able to create this with a little digging, which can serve as a decent template for a flow chart. For CLI, adding an argument -i means inner=True, else inner=False. Engineer & Side Project Junkie sharing what I am working on so readers like you can benefit from my experiences. This flow can be reversed by changing the order in which you define the nodes.
