Mermaid is a nicer alternative to my old practice of checking graphviz source and rendered diagrams into my repos

Sadly, it always completely messes up flowcharts for me that are more than 2 next to eachother. It starts placing blocks in "random" places like putting a 3rd level if the flow chart by the first level and having crazy arrows going around.

I prefer excalidraw or the diagrams.net plugin because of this.
