A baffling scale transform on a chart of university course selection trends
https://twitter.com/benmschmidt/status/1562489422503120896  It's a log scale centered on 100%, so that the relative positions of dots accurately shows their proportions relative to each other. E.g. "doubled" is the same distance from "stayed the same" as is "halved." A weird hills I choose to die on is that log scales are often better.
