"Concept map" ≠ "Mind map"

[divilian]

Describe the mistake
The book describes its (excellent) conceptual diagrams as "mind maps." Actually mind maps are trees, and concept maps are graphs (see, e.g., Stephen Davies. 2011. Still building the memex. Commun. ACM 54, 2 (February 2011), 80–88. https://doi.org/10.1145/1897816.1897840). What you have here are concept maps.
