Display draggable geo shapes on map
This example displays a moveable map with four geo shapes. These shapes can be moved around the map.
Four geo shapes, H.map.Polyline, H.map.Polygon, H.map.Circle, H.map.Rect
are placed on map. In order to respond to drag events the draggable flag needs to be set. In order to
have smoother resizing the object's volatility property should be set to true.
