A Half Donut Chart, also known as a Half Pie Chart, is a data visualization technique that represents data in a circular format, similar to a Pie Chart, but only half of a circle is filled with data. Half Donut Charts are useful for displaying percentages or proportions in a visually appealing and easy-to-understand manner, particularly when you want to emphasize a particular segment of the data or compare two categories.

The Half Donut example below is looking at Incidents by Priority.
