Nice work ! The digraphs makes it much more clear. I am not sure about a health bar, I don't want to flag packages with a red bar, just because they do complex stuff and need a lot of dependencies. A dependency counter, with maybe even a counter of the number of dependencies which status is passing (for github CI actions) would be top.
If there is an easy way to include a link to a dependency graph in our README.md, that could be nice too!
