Pie Chart
A pie chart is a circular chart that displays data as a series of wedges, with each wedge representing a proportion of the whole. The size of each wedge is proportional to the value of the data it represents, and the wedges are arranged in a circle to represent the total value of the data.
Pie charts are often used to display data as percentages, where the total value of the data is 100%. They are commonly used to show the relative sizes of different categories within the data, or to compare the sizes of different sub-categories within each category.
Pie charts are useful for displaying simple data sets with a small number of categories. They are easy to understand and can provide a quick overview of the data. However, pie charts can become difficult to read when there are too many categories or when the values of the categories are too similar. They can also be misleading if the sizes of the wedges are not accurately proportional to the values they represent.
