Pie charts present data through circular or semi-circular areas. The entire area is considered 100%, and then divided into different-sized sectors based on the proportion of each data category. Pie charts use different colors to distinguish each sector, allowing viewers to instantly see the proportion of each data type at a glance, making it a highly intuitive statistical chart. With Pie Chart Maker, you can create various types of pie charts, such as basic pie charts, donut charts, semi-donut charts, and Nightingale rose charts.
