pandas - 来自csv文件的Python饼图

Question

我正在尝试从 CSV 文件制作饼图，但它并没有达到预期的效果，因为我希望将国家数量的比较作为输出，代码如下：饼图的输出：

WHO Region  Country/Region (Count All)
Africa  48
Americas    35
Eastern Mediterranean   22
Europe  56
South-East Asia 10
Western Pacific 16

CSV 文件的链接

df2 = pd.read_csv('PC.csv')

df2.head()

df2 = df.rename(columns={"WHO Region":"WHO_Regions","Country/Region (Count 
All)":"Countries"})

df2.head(6)

data_pie=df2['WHO_Regions'].value_counts().rename_axis('WHO_Regions').reset_index(name='Countries')

plt.figure(figsize=(10,10))

plt.pie(data_pie.Countries, labels=data_pie.WHO_Regions, startangle=45,autopct='%1.1f%%')

plt.title('Count of Active cases')

plt.show()
