Introduction to Pie Charts:

A pie chart is a circular graph that represents data as slices of a pie.

It is used to show parts of a whole or the distribution of categories within a data set.

Constructing a Pie Chart:

Identify the categories or parts for which data is being represented.

Determine the central angle for each category based on its proportion to the whole.

Calculate the central angle using the formula: (Category value / Total value) x 360°.

Draw a circle and mark the central angles for each category.

Label each slice with the category name and its corresponding percentage or value.
