How to Add Google Charts on a Webpage?

What is a pie chart?
A pie chart (or a circle chart) is a circular statistical graphic which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented.

Applications of Pie chart

  • Pie charts are generally used to show percentage or proportional data of sales of different items in a business.

  • Used in surveys to depict no of items in each category.
