选中或者移入地图 城市后在上层的z序以当前城市的经纬度作为中心点 放大展示城市

[benmo1602]

What problem does this feature solve?

我通过echart 完成我的业务开发需求过程中发现 ，实现过于困难， 我先将所有的 子城市 注册， 然后鼠标移入的时候， 动态修改geo 或者series 这样 要重绘整个canvas 另外： 我在实现 静态绘制效果的时候 ， 子城市的 center 会按照整个画布和自身的path 重新 计算中心点

What does the proposed API look like?

series （map） 下的 zoom是 针对整个map的 ， 希望在 emphasis 添加 一个 scale属性 可以在上层 重新覆盖 一个城市， 并且 中心点是按照 当前 城市的物理中心点 实现，避免 跑偏的问题
