echarts实现地图
⽂章以河南省为例
⼀、先下载eacherts相关js⽂件（echarts.min.js）和echarts使⽤到的地图插件（map）
⼆、代码
<script type="text/javascript" src="/home/js/jquery.js"></script>
<script type="text/javascript" src="/home/js/echarts.min.js"></script>
<-- 我这⾥⽤的是河南地图，可以根据⾃⼰需要选择城市-->
<script type="text/javascript" src="/home/js/map/js/province/henan.js"></script>
<script>
<--地址换成从github下载的⽂件路径-->
var uploadedDataURL = "/home/js/map/json/province/henan.json";
myChart.showLoading();
$.getJSON(uploadedDataURL, function(geoJson) {
myChart.hideLoading();
var geoCoordMap = {
