What works against pie charts:
- Difficult to compare slice sizes & values, especially when they are close in size.
- Can unnecessarily take up the readers time trying to match each slice with the correct category.
- Can become messy.
- Can be easily manipulated to give false impressions
What works in their favor:
- Can be created quicker than your boss can blink.
- It’s a circle. which means it shows the full picture.
- Require minimal additional explanation.
A compromise has to be made. I find Stephen Few’s suggestion (see video) to be just that!
