I gave it a try on my current codebase out of curiosity. Definitely useful. It worked well and fast, but it has a lot of duplicates that get rendered as exports in the NodeJS modules based codebase. I think it can sometimes be caused by me just being haphazard about re-exporting them, but other times I'm not sure.

Eg authenticatedMenu() appears 4 times in authenticatedMenu.js, only one of them is imported by 2 different files and 3 are just there alone. There's a single export in the file and a number of other files import it through an index.js that re-exports several files other files too.

In my case I think it'd help, if I could disable the duplicates as they don't really provide any useful information when exploring the codebase.

Also, if there was optionally a way to ignore the files that re-export functions/classes and collapse those paths, it'd make the graph a lot smaller and more easy to understand. Maybe it's already something that depgraph does, but the duplicates confuse things, so I'm not sure.
