How Charts Work p 212
from: FT - The science behind good charts
1 - Pie charts
- FT asked people to identify the third biggest part of pie charts comparing with bar charts.
- For a magnitude comparison bar charts are generally better than pie charts
2 - Shapes - comparing length, area, volume
- How many times bigger shape A is than shape B?
- More complex shapes can present problems in data visualisation context
3 - Colour gradient - Visual Perception

increasing people’s awareness of the science behind data visualisation is key to increasing fluency in graphical communication.
