I've been experimenting with martinvonz/jj (aka Jujutsu), a newish version control system with some git compatibility.
One of the fun things is jj's language of revsets where there are shorthands for specifying ranges of commits. Well the descriptions were confusing, and light experimentation on my more or less linear history repos weren't too enlightening, so I went to the effort of creating a diagram using a more convoluted commit graph
