Ask HN: What are the best illustrations in a technical book you've seen?

Both of Robert Nystrom's books:

I liked the illustrations in the COCOMITE guidebook to professional tools, published by Trusco Nakayama in Japan. It’s online in English here:

(The title is from the Japanese ここ見て, koko mite = look here.)

The Machinery of Life by David S. Goodsell: https://ccsb.scripps.edu/goodsell/machinery-of-life/

Wow. There is a book on electrical work call (I think) Wiring Simplified, which I thought very good. Andrew Tannenbaum's book on operating systems (the one with Minix) had good illustrations, I thought.
