1. 效果图

2. npm下载echarts，在main文件中全局引入

npm install echarts -S

import * as Echarts from 'echarts'
app.config.globalProperties.$Echarts = Echarts;

4. vue文件中template

<div class="container">
    <img ref="dot" hidden src="../assets/map-bg.png">
    <div id="map" ref="map" style="height: 500px;"></div>
</div>

3. 通过阿里云数据可视化平台下载获取geoJson数据文件，在vue文件中引入该数据文件

import "echarts/map/js/china.js";

5. 实现直接贴代码

import { getCurrentInstance, ref } from 'vue';
// 获取当前组件实例下的proxy
const { proxy } = getCurrentInstance();
// 通过ref获取dom元素
const dot = ref(null)

const map = ref(null);

let myChart = proxy.$Echarts.init(document.getElementById('map'));
let options = {
    backgroundColor: "#040b1c",
    geo: {
        map: 'china',
        type: 'map',
        layoutCenter: ['50%', '50%'],
        layoutSize: '120%',
        zoom: 1,
        roam: false,
        itemStyle: {
            borderColor: '#AEF3FF',
            borderWidth: 2,
            areaColor: {
                image: dot.value,
                repeat: 'repeat'
            },
            shadowColor: 'rgb(58,115,192)',
            shadowOffsetX: 6,
            shadowOffsetY: 12
        }
    },
    series: [
        {
            type: 'map',
            map: 'china',
            layoutCenter: ['50%', '50%'],
            layoutSize: '120%',
            zoom: 1,
            roam: false,
            itemStyle: {
                borderColor: '#AEF3FF',
                borderWidth: 1,
                areaColor: {
                    image: dot.value,
                    repeat: 'repeat'
                },
            }
        }
    ]
}
myChart.setOption(options);
window.onresize = () => {
    myChart.resize()
}
