python 绘制河南省各市的疫情图

import json
from pyecharts.charts import Map
from pyecharts.options import*

#打开文件
f = open("D:/疫情.txt","r",encoding="UTF-8")
data = f.read()
#打开文件之后要记得关闭文件哦
f.close()
#数据类型转换
data_dict= json.loads(data)
#读取数据
cities_data_list = data_dict["areaTree"][0]["children"][3]["children"]
data_list=[]
for data_cities in cities_data_list:
    city_name=data_cities["name"]+"市"
    city_confirm = data_cities["total"]["confirm"]
    data_list.append((city_name,city_confirm))
data_list.append(("济源市",5))
#开始画图了哦
map = Map()
map.add("各市新冠疫情人数",data_list,"河南")
map.set_global_opts(
    title_opts = TitleOpts(title="河南疫情图"),
    visualmap_opts = VisualMapOpts(
        is_show=True,#是否显示
        is_piecewise= True,#是否分段
        pieces=[
            {"min":1,"max":20,"label":"1~20人","color":"#CCFFFF"},
            {"min":21,"max":40,"label":"21~40人","color":"#FFFF99"},
            {"min":41,"max":60,"label":"41~60人","color":"#FF9966"},
            {"min":61,"max":99,"label":"61~99人","color":"#CC3333"},
            {"min":100,"color":"#990033"}
        ]
    )
)
map.render()

这个和上期的不同之处在于，数据取得不同，全局设置和上期一样，完结撒花，Keep going！
