Chiu-Jain plots are great for getting a grasp of AIMD. Another related one I like is the figure illustrating ack-clocking in Van Jacobson's original congestion control paper - Figure 1 here: https://ee.lbl.gov/papers/congavoid.pdf

This is great indeed, and makes it for 2 illustrations from Van Jacobson's papers, separated by 28 years! (The 1988 paper and the 2016 BBR paper)
