3.15 ToDG: Data density and small multiples (1)


  • \(\text{Data density of a graphic} = \frac{\text{number of entries in data matrix}}{\text{area of data graphic}}\) (Tufte 2001, 2:168)

  • Further rules:

    • Maximize data density and the size of the data matrix, within reason
    • Graphics can be shrunk way down.
    • → small multiples
  • Figure 3.12, a small-multiples example, was published in Munzert and Bauer (2013).
