pyecharts圖表庫學習:Pie（餅圖）

餅圖主要用於表現不同類目的數據在總和中的佔比。每個的弧度表示數據數量的比例。
Pie.add()方法簽名

add(name, attr, value,
    radius=None,
    center=None,
    rosetype=None, **kwargs)
name -> str
	圖例名稱
attr -> list
	屬性名稱
value -> list
	屬性所對應的值
radius -> list
	餅圖的半徑，數組的第一項是內半徑，第二項是外半徑，默認爲 [0, 75]
	默認設置成百分比，相對於容器高寬中較小的一項的一半
center -> list
	餅圖的中心（圓心）座標，數組的第一項是橫座標，第二項是縱座標，默認爲 [50, 50]
	默認設置成百分比，設置成百分比時第一項是相對於容器寬度，第二項是相對於容器高度
rosetype -> str
	是否展示成南丁格爾圖，通過半徑區分數據大小，有'radius'和'area'兩種模式。默認爲'radius'
	radius：扇區圓心角展現數據的百分比，半徑展現數據的大小
	area：所有扇區圓心角相同，僅通過半徑展現數據大小
