// 秋雁南飞：
// 此版本通过设置geoindex && seriesIndex: [1] 属性来实现geo和map共存，来达到hover散点和区域显示tooltip的效果
// 默认情况下，map series 会自己生成内部专用的 geo 组件。但是也可以用这个 geoIndex 指定一个 geo 组件。这样的话，map 和 其他 series（例如散点图）就可以共享一个 geo 组件了。并且，geo 组件的颜色也可以被这个 map series 控制，从而用 visualMap 来更改。
// 当设定了 geoIndex 后，series-map.map 属性，以及 series-map.itemStyle 等样式配置不再起作用，而是采用 geo 中的相应属性。
// http://echarts.baidu.com/option.html#series-map.geoIndex
// 并且加了pin气泡图标以示数值大小
// // 全局变量区:参考江西绿色金融（谢谢：本来想用闭包实现接口数据调用，没时间了）
