Markers are notes that are used to leave a message on the Maps. It indicates or marks a specific location with desired symbols on the Maps. It can be enabled by setting the visible property of the markerSettings to true.
The dataSource property of the markerSettings has a list of objects that contains the data for Markers. Using this property, any number of markers can be added to the shape layers. By default, it displays the markers based on the specified latitude and longitude in the given data source. Each data source object contains the following list of properties.
markerSettings is an Array property.

To render a marker as an image in Maps, set the shape property of markerSettings as Image and specify the path of the image to imageUrl property.

Bind the field name that contains the path of the image in the data source to the imageUrlValuePath property.

</body></html>Maps provide support to hide and cluster markers when they overlap each other. The number on a cluster indicates how many overlapped markers it contains. If zooming any of the cluster locations in Maps, the number on the cluster will decrease and begin to see the individual markers on the map. When zooming out, the overlapping marker will increase so that it can cluster again and increase the count over the cluster.
To enable clustering in markers, set the allowClustering property of markerClusterSettings as true and customization of clustering can be done with the markerClusterSettings.
