Off topic, but that star plot was impossible to read. Straight up parallel coordinates would have been an improvement (maybe), but I can't help feeling like, with only 25 data points, a summary table would have been even better. I love visualizations as much as the next guy, but only when they are aids to understanding, not, you know, detriments to it.

I disagree. While it was impossible to understand any specifics, that wasn't what they were trying to show. Instead, they were trying to show how Tesla dominates over other EVs (that are all about the same). And it did a great job of showing that, much better than a table would have.

That's fair. I was conflating two things in my initial post: legibility and suitability. Legibility was atrocious; I did not get the same insight from the vis that you did because I couldn't read it. Suitability is, of course, debatable. I find star plots have a fair bit of noise (e.g., line slope) that detracts from the message of the vis. Parallel coordinates are slightly better in this regard, but still require a "discerning eye." However, looking at it again, I agree that a table would be insufficient.
