保存结果，三张图：

虽然数据来源于百度地图，为了学习，用python也做个地图：

"""
    首先是全国火锅店分布数量
"""
import pandas as pd
from pyecharts.charts import Map
from pyecharts.globals import ThemeType
import pyecharts.options as opts

data = pd.read_excel('各省总火锅店数量.xlsx') #用熊猫读取数据
# 提取出省份和数量
provinceList = data['省份'].tolist() # 将省份名称作为列表
num = data['数量'].tolist() # 将数量也做成列表
print(provinceList)

provinces = []
# 修正省份参数，因为pyecharts只支持前面有标识的字，内蒙古自治区要处理成内蒙古，广西壮族自治区要处理成广西
for i in provinceList:
    if '省' and '市' in i:
        provinces.append(i[:-1])
    elif '内蒙古' in i: # 处理内蒙古自治区为内蒙古
        neimenggu = i[0:3]
        provinces.append(neimenggu)
    elif '自治区' in i: # 处理类似广西壮族自治区和宁夏回族自治区之类的字符广西和宁夏
        provinces.append(i[0:2])
    else:
        provinces.append(i[:-1]) # 处理黑龙江省成黑龙江
# print(len(provinceList)) # 比较长度是否相等
# print(len(provinces)) # 比较长度是否相等

# 开始绘图
map = (
    Map(init_opts=opts.InitOpts(width='1280px',height='960px', theme=ThemeType.VINTAGE))
    .add('数量', [list(z) for z in zip(provinces, num)], 'china') # 中国地图
    .set_global_opts(
        title_opts=opts.TitleOpts(title='全国火锅店分布数量',),
        legend_opts=opts.LegendOpts(pos_left='10%', pos_top='10%')
    )
).render('全国火锅店分布数量.html')

运行截图：

 

 数据发现，全国火锅店数量最多的不是四川，而是山东，做下山东地图可视化：

"""
