Cool! More interesting, I didn’t know the dot utility for creating the visual representations of the graphs. I can think of a bunch of uses for that.

I use it for project management:

dot (part of graphviz) is super handy.

Thank you for referencing the package dot is in!

systemd-analyze(1) supports dot(1) output to plot dependencies between units:

Quoting from the man page:

    EXAMPLES FOR DOT
       Example 1. Plots all dependencies of any unit whose name starts with "avahi-daemon"

           $ systemd-analyze dot 'avahi-daemon.*' | dot -Tsvg > avahi.svg
                 $ eog avahi.svg

       Example 2. Plots the dependencies between all known target units

           systemd-analyze dot --to-pattern='*.target' --from-pattern='*.target' | dot -Tsvg > targets.svg
           $ eog targets.svg
