饼图主要用于表示不同分类的占比情况。饼图中的每个扇形切片表现一个分类，扇形切片的弧度表示该分类在整体中的占比，所有切片构成一个整体，即 100%。

饼图是一个饱受争议的图表类型，有人认为饼图看起来难以阅读，我们的视觉系统只能判断出一个切片比一个切片要大，但很难确定大多少。在一些极端的情况下，饼图各切片大小相近，饼图将变得失去其功能性。如果你也有这种担心的话，可以使用条形图代替。

The pie chart is mainly used to show the proportion of different categories. Each fan-shaped slice in the pie chart represents a category. The arc of the fan-shaped slice represents the proportion of the category in the whole. All slices form a whole, that is, 100%.

Pie charts are a controversial type of chart. Some people think that pie charts look difficult to read. Our visual system can only judge that a slice is larger than another, but it is difficult to determine how big it is. In some extreme cases, the slices of the pie chart are similar in size, and the pie chart will lose its functionality. If you have this concern, you can use a bar graph instead.
