I'm not sure we need the blow by blow account.

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:

Package: mate-desktop
Version: 1.16.2-2
Architecture: amd64
Replaces: mate-desktop-gnome
Depends: hicolor-icon-theme, libmate-desktop-2-17 (>= 1.10.0),
 mate-desktop-common (= 1.16.2-2), python, python-requests, libatk1.0-0
 (>= 1.12.4), libc6 (>= 2.4), libcairo-gobject2 (>= 1.10.0), libcairo2
 (>= 1.2.4), libgdk-pixbuf2.0-0 (>= 2.22.0), libglib2.0-0 (>= 2.28.0),
 libgtk-3-0 (>= 3.0.0), libpango-1.0-0 (>= 1.14.0), libpangocairo-1.0-0
 (>= 1.14.0), libstartup-notification0 (>= 0.2), libxrandr2
Recommends: mate-user-guide
Breaks: mate-desktop-gnome

Yes, it's often difficult to follow explanations of GUI processes
because they're interactive by nature. Sometimes a video is more
help than written instructions. The modern world …
