What is a pie chart?

A pie chart, also known as a circular chart, is a type of chart that is used to represent data in a circular format. It is used to show the proportion of different categories in a whole. The chart is divided into segments, with each segment representing a specific category and the size of the segment representing the proportion of that category within the whole.

The chart is divided into wedges, with each wedge representing a category of data. The size of the wedge corresponds to the proportion of the category within the whole. The total of all wedges in a pie chart should always equal 100%.

Pie charts are particularly useful when comparing the proportion of different categories within a whole. For example, a pie chart can be used to show the market share of different brands of a product, or the proportion of different types of expenses in a budget.

One of the main advantages of a pie chart is that it is easy to understand and interpret. The human eye is naturally drawn to the size of the wedges, making it easy to compare the proportions of different categories.

However, pie charts also have some limitations. They can be difficult to read when there are too many categories or when the categories are very similar in size. Additionally, it can be difficult to compare the exact values of the categories, as the wedges are not labeled with numerical values.

It is easy to understand and interpret, but it has some limitations when dealing with many categories or small differences between them.
