Advanced diagrams (PlantUML/C4)

[RLogik]

It would be very useful to implement more advanced paradigms, e.g. for software architecture. There are a few options here, e.g.

• PlantUML
• C4

See e.g. https://github.com/adrianvlupu/C4-PlantUML, https://github.com/plantuml-stdlib/Azure-PlantUML.

Here is what PlantUML looks like:

The C4 paradigm is documented here: https://mermaid.js.org/syntax/c4.html. C4 in itself does not look very nice, but the combination with PlantUML seems decent and looks like this:

What is missing is symbols for Databases, etc.

C4 in itself does not look very nice

Care to elaborate? The C4 model doesn't prescribe any notation.

put into #1661 since we will support C4 after we upgrade our mermaid library dependency.

plantUML refers #1246
