How to Create Markers with the React Maps Component?

This article explains how to create markers with the React Maps component.

The Syncfusion React Maps component supports adding markers to represent specific geographic locations on the map. Each marker is associated with a pair of latitude and longitude coordinates, allowing users to highlight places of interest, such as cities, landmarks, or other location-based data. This section explains how to create maps with markers in a React application using the Syncfusion Maps component.

Markers are added to the map using the dataSource property within the MarkerDirective tag. This property contains a list of objects that represent the marker locations with latitude and longitude values, along with any additional data. To enable this feature, set the visible property to true in the MarkerDirective tag. The rendered markers can be customized using the properties within the MarkerDirective tag.

The following code sample demonstrates how to add a marker in React Maps.
