Donut graphs, also known as donut charts, are a type of graph that is used to display data in a ring format. They are similar to pie charts, but donut charts have a hole in the center that can be used to display additional information. Keep reading to learn more about donut charts and how you can interpret and use them.

## What are donut graphs?

A donut graph, similar to pie charts, is a graphical representation of data in which the area of each slice is proportional to the quantity it represents. In other words, the total area of the chart is divided into slices that represent different data points, and each slice is sized according to how much of the whole it represents.

Donut charts are used to illustrate how a particular subset contributes to a whole. Donut charts work by calculating what percentage each slice of data represents out of the total. This percentage is then used to determine the size of the slice. For example, if you have a donut chart with five slices, and one slice represents 25 percent of the total, that slice will be larger than all of the others.

## How can you read donut graphs?

When looking at a donut chart, it is important to understand what the colors and sections mean. The colors usually indicate how well a company is doing in comparison to others, while the sections usually show the company’s performance in different areas. For example, a donut chart that is blue all around with a small green section in the middle may mean that the company is doing well overall but is not as strong in terms of sales or profits as some competitors. A donut chart that is mostly red with a small green section in the middle may mean that the company is doing poorly overall but is doing well in terms of sales or profits. Pay attention to the different colors and sections when reading a donut chart to get an accurate understanding of how the company is performing overall.

## What are the uses for a donut graph?

Donut charts can be used in a variety of ways to analyze data, but typically they are used to show how a portion of a whole is divided. This can be done by illustrating the percentage of a whole that is made up of different slices or by illustrating the size of each slice in comparison to the whole.

Donut charts can be helpful for displaying data that is difficult to compare using a traditional bar or line chart. For example, the percentage of men and women in different age groups can be easily compared using a donut chart. In the example below, the donut chart on the left shows that there are more men aged 20-29 than women in that age group, while the donut chart on the right shows that women aged 60 and over make up the majority of the population in that age group.

Donut charts can also be used to compare the size of different slices. In the example below, the donut chart on the left shows that the slice for people aged 30-39 is larger than the slices for people in any other age group. The donut chart on the right shows that the slice for people in the age group of 40-49 is larger than the slices for people in any other age group.

Overall, donut charts are an important tool to help visualize data. They are easy to understand and can be used to compare data sets or show progress over time.
