Explain: How to draw Pie chart?
Steps to draw pie chart :
Pie chart is a circular graph which is used to represent data. In this :
- Various observations of the data are represented by the sectors of the circle.
- The total angle formed at the centre is 360°.
- The whole circle represents the sum of the values of all the components.
- The angle at the centre corresponding to the particular observation component is given by,
$\frac{Value of the component}{Total value} \times 360°$
Therefore, based on the given data and using the above formula we can construct a pie chart.
Note that the sum of all the angles at the centre should be equal to 360 degrees.
