What is Donut Chart?
A donut chart is a pie chart variation and – simultaneously – the attempt of fixing its issues.
Pie charts are widely criticized for the difficulty in comparing the slices to one another and the chart as a whole, which can lead to mistakes in conclusions.
Why donut chart is better than a pie chart?
Donut charts (also called doughnut charts) are simply pie charts with blank centers. This shape allows for additional information about the data to be included. This way, users can focus more on reading the length of the arcs rather than comparing the slices’ proportions.
They aim to illustrate proportions, just as pie charts, and can also be supportive in statistics. As opposed to pie charts, they provide a better data intensity ratio center.
Donut charts are also more efficient in terms of space than pie charts, as the blank center can display additional information.
