taro+react uses techarts and echarts to implement a map of China

The first step is to download the package

 cnpm i echarts techarts -D

The second step is to introduce plugins and China map

import EChart from 'techarts';
import * as echarts from 'echarts'
import 'echarts/map/js/china'

The third step is to set the option and instantiate the component

const option ={
    
    
    title : {
    
    
        text: 'iphone销量',
        subtext: '纯属虚构',
        left: 'center'
    },
    tooltip : {
    
    
        trigger: 'item'
    },
    legend: {
    
    
        orient: 'vertical',
        left: 'left',
        data:['iphone']
    },
    visualMap: {
    
    
        min: 0,
        max: 2500,
        left: 'left',
        top: 'bottom',
        text:['高','低'],           // 文本，默认为数值文本
        calculable : true
    },
    toolbox: {
    
    
        show: true,
        orient : 'vertical',

Can finally show
