Looks great! Since it's programmable in Go, why not go whole hog ? 1) Accept an SQL schema and automatically diagram all tables that interconnect via PK/FK ref

Looks great! Since it's programmable in Go, why not go whole hog ? 1) Accept an SQL schema and automatically diagram all tables that interconnect via PK/FK references (including many-to-many). 2) Starting from main(), reflect a compiled code base (or use source files' parse results from https://pkg.go.dev/go/parser https://pkg.go.dev/go/parser) and diagram it down to some level.
