The marker clustering utility helps you to manage multiple markers at different zoom levels.When a user views the map at a high zoom level, the individual markers show on the map. When the user zooms out, the markers gather together into clusters, to make viewing the map easier.
If you have a lot of markers on the map, it’s better to use Marker Cluster setting to organize them better visually.
