Pie charts show how different groups contribute to a total. They are typically used to break down important numbers so that we can see the main contributors.
When To Use a Pie Chart
Pie charts are really useful for viewing what percentage each group of data contributes to a total.
For example, if you have an e-commerce store. A pie chart showing the number of sales from each product will show you what items bring in the most sales. This would allow you to figure out what product to focus on.
