Introduction
A pie chart uses "slices" of a circle to represent proportions. In a pie chart, the angle at the centre of each "slice" is proportional to the quantity it represents.
Example

| European | 156 | 78 |
| Maori | 24 | 12 |
| Other | 13 | 6.5 |
| Pacific | 7 | 3.5 |
| Overall | 200 | 100 |
