Generate Mermaid diagrams

[GrimPixel]

Mermaid diagrams can be utilised to visualise the entire code execution procedure in different ways, I think.

Interesting. Mermaid is a format I like a lot for its simplicity and usefulness, and on top of that it is also supported by GitHub. It seems like a nice feature to have. I'll consider it, but it is not a priority, so it is something for the future.

I do understand its usefulness though. The graphs can already be exported as images that can be used almost anywhere, but a mermaid diagram is more compact and provides a more simplified view of the relationships between the nodes.
