Nice, thank you. The diagrams were correct but the choices of colors, line widths and fonts have room for improvement.
Agree the formatting is not great. The tool is not intended to be 'perfect', with respect to formatting or to content, so if I continue working on this, I think the most useful step would be to add "export to Figma" -- and let you tweak there. I think this is most useful as a very fast prototyping tool.
