For a super basic comparison and out of curiosity, I’ve taken a scatter plot and bar chart from the documentation of different libraries. Note that this neglects many things like the fact that fine-tuning would probably allow for “prettier” graphs. Also, it doesn’t say much about how easy users can change the appearance, but it is still nice to look at.
