Adding animated lines to maps

Polylines are the representations of Earth's features on the Earth, but sometimes, they are not enough to show the mobility of Earth features. For example, a river can be shown with the help of polylines, but the flow direction of the river can't be demonstrated by the polylines alone. Animating polylines can be a solution to show the mobility of Earth features. The flow direction of a river can be shown with the help of animated polylines.

The Google Maps JavaScript API has a symbol feature that can add vector-based images to a polyline in the form of a symbol. You can create your own symbol with the help of the Symbol class, or you can also use the predefined symbols that are accessed from the SymbolPath class.
