A review of "The Back of the Napkin: Solving Problems and Selling Ideas with Pictures" — 3 years ago
Describes how to use diagrams and drawing within a problem solving and presentation / explanation framework. This is something that bridges the gap between somewhere between Visual Explanations, Making Comics, and How to Solve It, with some dashes of Beyond Bullet Points or whatever your favorite presentation book is.
A quick read, and maybe worth it if you are stuck thinking about how to make your problem more visual for explanation, or if you have a lot of information you need to organize.
