Underscores stripped from clustered package names

Is there any particular reason why the line of code referenced below strips underscores from clustered package names? It makes the nodes harder to read for me.

pydeps/pydeps/render_context.py

Line 295 in 2c0b958

return n.split('.')[0].replace('_', '')

Ah, an especially well-documented function :-D

If I remember correctly, it is to satisfy the naming constraints on subgraph in graphviz (https://github.com/thebjorn/pydeps/blame/2c0b958b2f4dd6e00f59b37e63c218d53e6e1773/pydeps/render_context.py#L237), but it is probably a bug that the next line uses the cluster id for the label text...

Simply commenting out the .replace('_', '')-part of the line solved the problem for me. There seemed to be no problem with cluster-ID constraints. Maybe something changed in Graphviz?

Any progress on this one ? Any chance this gets fixed in some future release ?

Check out v1.12.4 available on PyPI.
