84. Piecharts are the information visualization
equivalent of a roofing hammer to the
frontal lobe. They have no place in the world
of grownups, and occupy the same semiotic
space as short pants, a runny nose, and
chocolate smeared on one’s face. They are
as professional as a pair of assless chaps.

89. Tables are preferable to graphics for many small
data sets. A table is nearly always better than a
dumb pie chart; the only thing worse than a pie
chart is several of them, for then the viewer is
asked to compared quantities located in spatial
disarray both within and between pies… Given
their low data-density and failure to order
numbers along a visual dimension, pie charts
should never be used.

115. Cleveland’s three visual operations
of pattern perception:
1. Detection
2. Assembly
3. Estimation
182. Q: Should I include 0 on my scale?
A: It depends.
183. Q: Should I include 0 on my scale?
A: Relying on the pre-attentive
perception of size or intensity?
Yes, otherwise you will mislead.
Using position? It’s up to you.
