Creating an Interactive Map with ECharts in React: A Guide for Any Country

This article provides a guide on creating an interactive map using ECharts in React. Interactive maps are essential for visualizing geographical data effectively. In this tutorial, we use Turkey’s map as an example, but you can load any country’s JSON file to display its map. This guide is flexible and allows you to customize the map data for any country of your choice.

Before you start, make sure you have a basic understanding of React and have set up your development environment. To get started with ECharts, first, install the package by running the following command in your project:

npm install echarts echarts-for-react

You can load the map data from a JSON file that contains geographic information for any country. Replace the file path with your desired country’s map data. For example:

const countryMapData = require("../../MapJson/countryList.json");

Let’s create a functional component to render the map:

import React, { useEffect, useState } from "react";
import ReactECharts from "echarts-for-react";
import * as echarts from "echarts";

const countryMapData = require("../../MapJson/countryList.json");

export const CountryProgressMap: React.FC = () => {
  const [isMapRegistered, setIsMapRegistered] = useState(false);

  useEffect(() => {
    echarts.registerMap("COUNTRY", countryMapData); // Replace "COUNTRY" with the name of your country
    setIsMapRegistered(true);
  }, []);

  const chartOptions = {
    geo: {
      map: "COUNTRY", // Replace with the country name
      roam: true,
      itemStyle: {
        areaColor: "#e7e8ea",
      },
    },
    tooltip: {},
    legend: {},
  };

  if (!isMapRegistered) {
    return <div>Loading map...</div>;
  }

  return <ReactECharts option={chartOptions}/>;
};

You can further customize the chartOptions variable to suit your needs.

In this article, we demonstrated how to create an interactive map using ECharts in a React application. This approach is flexible and allows you to visualize data for any country by simply updating the map data.
