使用pyecharts.charts绘制非洲地图

要使用pyecharts绘制非洲地图，需要先安装pyecharts和pyecharts_maps模块。可以使用以下命令安装：

pip install pyecharts
pip install pyecharts_maps

然后，可以使用以下代码绘制非洲地图：

from pyecharts import options as opts
from pyecharts.charts import Map

        ('Cameroon', 24.6), ('Cape Verde', 0.5), ('Central African Republic', 4.5),

        ('Egypt', 98.4), ('Equatorial Guinea', 1.3), ('Eritrea', 3.5),
        ('Ethiopia', 114.9), ('Gabon', 2.1), ('Gambia', 2.3),

        ('Uganda', 44.2), ('Western Sahara', 0.6), ('Zambia', 17.7),
        ('Zimbabwe', 14.4)]

# 创建Map对象
map = (
    Map()
    .add("GDP per capita", data, "Africa")
    .set_global_opts(
        title_opts=opts.TitleOpts(title="非洲各国GDP人均表现"),
        visualmap_opts=opts.VisualMapOpts(max_=200),
    )
)

# 渲染图表
map.render("africa.html")

运行完毕后，会生成一个名为"africa.html"的html文件，里面包含绘制好的地图。
