模擬3D地圖——遷徙圖

var uploadedDataURL = "/asset/get/s/data-1528971808162-BkOXf61WX.json";

/**
此版本通過設置geoindex && seriesIndex: [1] 屬性來實現geo和map共存，來達到hover散點和區域顯示tooltip的效果

默認情況下，map series 會自己生成內部專用的 geo 組件。但是也可以用這個 geoIndex 指定一個 geo 組件。這樣的話，map 和 其他 series（例如散點圖）就可以共享一個 geo 組件了。並且，geo 組件的顏色也可以被這個 map series 控制，從而用 visualMap 來更改。
當設定了 geoIndex 后，series-map.map 屬性，以及 series-map.itemStyle 等樣式配置不再起作用，而是采用 geo 中的相應屬性。

並且加了pin氣泡圖標以示數值大小
