1. The y-axis does not start at zero.
2. The human figures guide the eye/brain to think of area, which is proportional to the square of height, rather than height itself.
3. No data details are given in the caption – 20-year-olds? Year of sampling? Multiracial?
A truly great book is The Visual Display of Quantitative Information by E.R. Tufte (who has written other books on the theme).
