echarts大屏可视化，HTML+CSS加载全国、或某一省市（安徽省）（各个省市县）地图_html+css大屏页面开发 后面的地图怎么写

echarts加载全国、或某一省市（安徽省）（各个省市县）地图：
全国地图大屏demo实例下载
安徽省地图大屏demo实例下载

先看一下效果图

1.地图的生成：
mapJson.json的生成。访问网址http://datav.aliyun.com/portal/school/atlas/area_selector
根据自己想要加载的范围选择，如安徽省


然后点击右侧的网址复制到浏览器访问


得到地图json，保存为mapJson.json供调用。

(function (root, factory) {
    if (typeof define === 'function' && define.amd) {
        // AMD. Register as an anonymous module.
        define(['exports', 'echarts'], factory);
    } else if (typeof exports === 'object' && typeof exports.nodeName !== 'string') {
        // CommonJS
        factory(exports, require('echarts'));
    } else {
        // Browser globals
        factory({}, root.echarts);
    }
}(this, function (exports, echarts) {
    var log = function (msg) {
        if (typeof console !== 'undefined') {
            console && console.error && console.error(msg);
        }
    }
    if (!echarts) {
        log('ECharts is not Loaded');
        return;
    }
    if (!echarts.registerMap) {
        log('ECharts Map is not loaded')
        return;
    }
   echarts.registerMap('anhui', ../common/mapJson.json);
}));

2.地图加载html的地图窗口写好，然后用javascript调用即可：

function map() {
        // 基于准备好的dom，初始化echarts实例
        var myChart = echarts.init(document.getElementById('map_1'));

上图中的各个地市（省、县）的中心坐标可在json中获取，用来标注圆形数值的位置。
