React 使用recharts实现散点地图的示例代码

npm install recharts

yarn add recharts

import React,{Component} from \'react\';
import {message} from \'antd\';
import echarts from \"echarts\";
import {mapJson,geoCoordMap} from \'./chinaJSON.js\';

import React,{Component} from \'react\';
import {message} from \'antd\';
import echarts from \"echarts\";
import {mapJson,geoCoordMap} from \'./chinaJSON.js\';

const convertData = (data) => {
  var res = [];
  for (var i = 0; i < data.length; i++) {
    var geoCoord = geoCoordMap[data[i].name];
    if (geoCoord) {
      res.push({
        value: geoCoord.concat(data[i].value),
        name: data[i].name,
      });
    }
  }
  return res;
};
