How Humans see data

Nov 20, 2023

Lovely talk by John Rauser at Velocity Conference:

Ordering elementary tasks by accuracy, according to theoretical arguments and experimental results. Graphs should exploit tasks as high in the ordering as possible. The tasks are ordered from most accurate to least:

  1. Position along a common scale
  2. Position on identical but nonaligned scales
  3. Length
  4. Angle
  5. Slope (with ϴ not too close to 0, pi/2 or pi radians)
  6. Area
  7. Volume
  8. Density
  9. Color Saturation
  10. Color Hue
