that is problem.

Add   -o APT::Cache::GivenOnly=1   to the commandline, and you'll get
a much smaller graph. I haven't figured out why python and
python-requests are missng from the graph, or is this a stretch/buster
difference. (I'm comparing the graph with the Packages entry:

gave useful output.

I'll do some reading and try on something simpler.
