echart4.9 实现map地图

1.需要引入echart.js以及chain.js

<script type="text/javascript" src="js/echarts.min.js"></script>
<script type="text/javascript" src="js/china.js"></script>

html:

<div class="chart-box">
   <div id="main" style="width:100%;height:95%;"></div>
</div>

script：

<script type="text/javascript">
    function randomData() {  
        return Math.round(Math.random()*500);  
    }
    var mydata = [  
        {name: '北京',value: '100' },{name: '天津',value: randomData() },  
        {name: '上海',value: randomData() },{name: '重庆',value: randomData() },  
        {name: '河北',value: randomData() },{name: '河南',value: randomData() },

        tooltip : {

        },
        
        //左侧小导航图标
        visualMap: {

        //配置属性
        series: [{
