This sent me down a rabbit hole since it’s something I’ve half-considering for a while. I prefer text configuration rather than GUI so I ended up installing graph-easy on my debian laptop:
sudo apt install libgraph-easy-perl
and made a first attempt to diagram the power setup in my campervan
It’s a perl module but the graph-easy
wrapper makes it behave like any other CLI tool. cat or echo the config text to the wrapper and the graph pops out on STDOUT
Neat concept. I got killed by the statue. :-/
