Hi @JetsettingJames, thanks for the PR. I took a look at the diagram that was generated by your tool. The tool itself looks cool but the digram that it produced doesn't fully match the way this repo works and it would cause confusion for someone new looking at the diagram.

I dont think we can accept this PR as it is today but as your tool develops and improves we could look at it again in the future.
