使用pyecharts.charts Geo绘制非洲地图

你可以按照以下步骤使用 pyecharts.charts Geo 绘制非洲地图：

1. 安装 pyecharts 库：可以使用 pip 命令进行安装。

2. 导入需要的库：

   from pyecharts.charts import Geo
   from pyecharts import options as opts
   from pyecharts.globals import ChartType, SymbolType

3. 准备数据：需要准备每个国家对应的数据。

   data = [
       ("Algeria", 121),
       ("Angola", 11),
       ("Benin", 0),
       ("Botswana", 2),
       ("Burkina Faso", 2),
       ("Burundi", 0),
       ("Cameroon", 21),
       ("Cape Verde", 0),
       ("Central African Republic", 0),
       ("Chad", 4),
       ("Comoros", 0),
       ("Congo", 7),
       ("Cote d'Ivoire", 19),
       ("Djibouti", 0),
       ("Egypt", 217),
       ("Equatorial Guinea", 0),
       ("Eritrea", 0),
       ("Ethiopia", 8),
       ("Gabon", 2),
       ("Gambia", 0),
       ("Ghana", 7),
       ("Guinea", 0),
       ("Guinea-Bissau", 0),
       ("Kenya", 14),
       ("Lesotho", 0),
       ("Liberia", 0),
       ("Libya", 68),
       ("Madagascar", 0),
       ("Malawi", 0),
       ("Mali", 0),
       ("Mauritania", 2),
       ("Mauritius", 0),
       ("Morocco", 105),
       ("Mozambique", 0),
       ("Namibia", 2),
       ("Niger", 3),
       ("Nigeria", 267),
       ("Rwanda", 0),
       ("Sao Tome and Principe", 0),
       ("Senegal", 3),
       ("Seychelles", 0),
       ("Sierra Leone", 0),
       ("Somalia", 0),
       ("South Africa", 177),

       ("Uganda", 0),
       ("Western Sahara", 0),
       ("Zambia", 3),
       ("Zimbabwe", 4),
   ]

4. 创建 Geo 实例，并设置参数：

   geo = (
       Geo()
       .add_schema(maptype="非洲")
       .add(
           "非洲国家",  # 图例名称
           data,  # 数据
           type_=ChartType.EFFECT_SCATTER,  # 散点图
           color="red",  # 散点颜色
           symbol_size=16,  # 散点大小
           label_opts=opts.LabelOpts(is_show=False)  # 隐藏标签
       )
       .set_series_opts(
           # 鼠标悬停效果
           label_opts=opts.LabelOpts(formatter="{b}"),
           tooltip_opts=opts.TooltipOpts(formatter="{b}: {c}")
       )
       .set_global_opts(
           # 标题
           title_opts=opts.TitleOpts(title="非洲地图"),
           # 显示工具栏
           toolbox_opts=opts.ToolboxOpts(is_show=True),
           # 鼠标缩放和平移
           visualmap_opts=opts.VisualMapOpts(is_piecewise=True),
           # 显示背景
           graphic_opts=[
               opts.GraphicGroup(
                   graphic_item=opts.GraphicItem(
                       # 图片地址
                       graphic_type="image",
                       graphic_shape_coords=[0, 0, 400, 400],
                       graphic_basicstyle_opts=opts.GraphicBasicStyleOpts(
                           fill="#fff"
                       ),
                       graphic_style_opts={
                           "image": "https://s3-us-west-2.amazonaws.com/s.cdpn.io/15309/world-map.png"
                       }
                   )
               )
           ]
       )
   )

5. 渲染图表：

   geo.render("africa.html")

这样就可以生成一个名为 africa.html 的文件，用浏览器打开即可显示非洲地图。
