The idea of a pie chart
The idea of a pie chart
- A pie chart represents data by dividing a circle into parts called sectors, so that the angle of each sector is proportional to the value it represents.
- The angles of all the sectors add up to 360°, because together they form the whole circle.
- Pie charts are usually used to compare parts of a whole, such as how a family spends its money or what a group of pupils chose.
