### Handle Mouse Control Start Event (JavaScript)

Source: https://www.esmap.cn/docs/sdk3.0/-tutorial/map-event

Listens for the 'controlstart' event, which fires when a user begins interacting with the 3D scene using mouse controls such as clicking or rotating. This event can be used to prepare the scene or UI for user input.

```javascript
map.on('controlstart', function () {
   // 鼠标开始操作三维场景后触发，例如点击、旋转等。
});
```

### Creating and Adding Effect Markers

Source: https://www.esmap.cn/docs/sdk3.0/-tutorial/effects-marker

Illustrates how to create an instance of an effect marker and add it to an effect layer. This example uses the CIRCLE_ROTATE type but can be adapted for others. A callback function can be provided for actions upon successful creation. The marker is then added to the layer using `layer.addMarker()`.

```javascript
// 创建一个特效标注
var marker = new esmap.ESEffectTool.EffectMarker(esmap.ESMarkerType.CIRCLE_ROTATE, {
    x: 12629907.4, 
    y: 2580180.5,
    height: 1,
    callback: function(){}
});

layer.addMarker(marker); // 将特效marker添加到特效层
```
