Graph generation using a crate

[andrewdavidmackenzie]

Instead of a lot of print statements, use a crate for graph creation and then dot file generation.

Something like https://docs.rs/dot/0.1.4/dot/

Or https://github.com/besok/graphviz-rust

Or https://docs.rs/petgraph/latest/petgraph/dot/struct.Dot.html

Maybe remove from the compiler completely and have a separate tool able to create the SVG from a compiled manifest.json

Or try D2 instead of graphviz https://github.com/terrastruct/d2
