Expose --graph/--node/--edge CLI options on dependencies command for injecting GraphViz attributes

[regexident]

I've thought about exposing more graphviz settings (i.e. shape, splines, …) as CLI options but ended up not doing it as one would quickly accumulate a massive amount of options (each with their own reasonable rational on why it should be included), while making it hard to see the forest for the trees, when reading --help. That said I too would like to be able to inject configurations into the generated .dot files without having to manually edit the output afterwards.

Maybe having generalized CLI options for the dependencies command for graph/node/edge default attributes that accept a comma-separated list of key-value pairs would be an acceptable compromise though:

• --graph "rankdir='LR', …"
• --node "shape='box', …"
• --edge "weight=2, …"
