`cabal-plan dot` for internal dependencies only

[peterbecich]

I believe cabal-plan dot generates a visualization of all internal and external dependencies.

Can a visualization restricted to internal dependencies be implemented?

Internal-only dependency visualization is a useful feature of Stack: https://docs.haskellstack.org/en/stable/dependency_visualization/

Thank you

For example take optics repository

cabal-plan --hide-global --hide-builtin dot-png

generates
