Why HN recommends it
Geometric, picture-driven treatment of complex analysis that builds intuition where most texts are purely algebraic; praised for clear explanations (e.g. the Riemann sphere) and suits curious learners.
Common criticism: Proofs are sketchy, so it works better as a supplement to a standard text
Summarised by Claude from recommending comments
This approach to complex analysis aims to replace the standard calculational arguments with new geometric arguments. With several hundred diagrams, this is a visual intuitive introduction to complex analysis. The book is designed for use by undergraduates in mathematics and science.

on “Ask HN: Are there books for mathematics like Feynman's lectures on physics?” ↗A few that come to mind immediately: 1. Books by VI Arnold. To get a sense of his style, see https://www.uni-muenster.de/Physik.TP/~munsteg/arnold.html 2. Visual Complex Analysis by Tristan Needham is an absolute treat in visual intution. 3. The road to reality by Roger Penrose. This is an absolute masterpiece building up to cutting edge physics and all the necessary math from…
on “Ask HN: Math books you recommend just for the way they are written?” ↗…http://en.wikiquote.org/wiki/John_von_Neumann That point of view makes a lot of sense to many of the best mathematicians. One more example of really interesting visual explanations of mathematical concepts is Visual Complex Analysis http://usf.usfca.edu/vca/ by Tristan Needham. The book is delightful, and well reviewed, but it is not the sole path toward getting used to complex analysis.

on “Ask HN: Good material for a gentle introduction to calculus with complex numbers?” ↗Visual Complex Analysis - Needham. A lot of great pictures, exerything is explained (and shown) geometrically.

on “Ask HN: What's the best textbook you've read?” ↗People that like this article might be interested in 'Visual Complex Analysis' by Tristan Needham. It's (IMHO) a rare book of collections of "concrete" analogies for complex analysis.
