Great visual, but one thing I've noticed is that LLMs have taken most of the "magic" out of creating these sorts of visualizations. Usually, it required a large amount of dedication to the subject matter, teaching techniques, and graphic design. Now, anyone with a passing knowledge can make them. Not saying that's a negative by any means, but that large dedication usually meant that you could trust the author's work and that it wouldn't have any hallucinations. Now, I find myself reading these more on the defense that it could be wrong about something, and I can't even trust them at all if I don't know anything about the subject already.

Every second paragraph, it seems very impressed to re-discover that CQT matches human aural perception.

Unfortunately, I have a faint recollection that CQT was expressly designed to match human aural perception, which leaves me markedly less perpetually astonished.
