pyecharts包绘制Map地图(笔记)

最近写文章,需要绘制地图,开始想用Tableau做,但是Tableau绘制某些地图不太方便,需要边界经纬度,于是找到了pyecharts
由于pyecharts版本更新,以前的代码不兼容新版本

pyecharts的中文官方文档(http://pyecharts.org/#/zh-cn/geography_charts)
通过作者给出的例子就可以快速上手,感谢作者!

pyecharts包安装

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyecharts

下载地图包:

pip3 install echarts-countries-pypkg

pip3 install echarts-china-provinces-pypkg

pip3 install echarts-china-cities-pypkg
