How we read pie charts is still an open question: is it angle? Is it area? Is it arc length? In a study I'm presenting as a short paper at the IEEE VIS conference in Vancouver next week, I tried to tease the visual cues apart – using modeling and 3D pie charts.

eagereyesTV Episode 2: Unit Charts, Dot Plots, ISOTYPE, and What Makes Them Special
Charts usually show values as visual properties, like the length in a bar chart, the location in a scatterplot, the area in a bubble chart, etc. Unit charts show values as multiples instead.

They’re an interesting family of charts and they seem to have some unusual properties that most other charts don’t have.
