Has anyone tried to make complex visualizations with Penrose that would mirror some of the graphics in https://www.amazon.com/Visual-Complex-Analysis-Tristan-Needh...

While I do see the value in a programmatic diagram tool, I'm not sure I'll use it over something like Inkscape if the visualization is fairly simple.

if you are interested in new insights about complex numbers and analysis from a geometric POV, this book is wonderful: http://www.amazon.com/Visual-Complex-Analysis-Tristan-Needha... and quite accessible.

Another beautiful math book is Visual Complex Analysis, http://www.amazon.com/Visual-Complex-Analysis-Tristan-Needha... Too many modern math texts are utterly alegebraic. VCA embraces geometry to great effect.
