Learning Graph

A learning graph is a map of every idea in this book and which ideas you need first. Each of the 368 concepts is a node. An arrow from one concept to another means "learn this one first". For example, Diwali points to Lunisolar Calendar, because you need the calendar to understand why Diwali moves each year.

The graph keeps the book honest: no chapter uses an idea before the book has taught it.
