- A donut chart is a type of chart that is similar to a pie chart, but with a hole in the center. It is often used to show the proportion of data that falls into different categories.
- Donut charts can be useful for visualizing data when you want to show the relationships between multiple categories, but you don’t want to clutter the chart with too much information. They are also useful when you want to show the data in a more visually appealing way, as the hole in the center of the chart can make it more aesthetically pleasing.
- To create a donut chart, you need to have data that can be divided into categories. Each category will be represented by a slice of the donut chart. The size of the slice will be determined by the proportion of the data that falls into that category.
