#### Event Handling

Google Map widget does not support any event.

#### Example <a href="#example" id="example"></a>

If we configure Google map Widget as below:

1. key - mapKey
2. Marker type - circle
3. Marker color - red

and set source type for widget as MQTT and topic configured is 'data'. And if we publish following JSON Object over 'data' topic then Google Map Widget will look as shown in image.

```
// Data over configured MQTT Topic

{
    "mapKey": {"lat": 15.78, "lng": 78.12}
}
```
