 * **Context**: In the below example, have three marker groups—France, India, and the USA. Each country contains many locations spread across different states. Displaying every location marker at the world level makes the map cluttered and hard to read.
 
 * **What clustering does**:
-At a world zoom level, markers that collide within each country’s group are clustered into a single symbol per group (e.g., one cluster for France, one for India, one for the USA). The cluster icon can display the count of locations it represents. As the user zooms in on a country, the single country-level cluster splits into smaller clusters based on proximity. For example, France’s cluster breaks into clusters around Paris and Normandy, and further zooming reveals the Eiffel Tower, the Louvre, and Notre-Dame as individual markers. The same behavior applies to India (e.g., clusters for Rajasthan, Uttar Pradesh, etc.) and the USA (e.g., clusters for Arizona, Nevada, Tennessee, and so on).
+At the world zoom level, markers that are geographically close are clustered into a single symbol per region (e.g., France, India, the USA). The cluster icon can display the number of locations it represents. As the zoom level increases, a country-level cluster splits into smaller clusters based on proximity, and continued zooming reveals individual markers. For example, France splits into clusters around Paris and Normandy, and further zooming shows individual points such as the Eiffel Tower, the Louvre, and Notre‑Dame. The same behavior applies to India (e.g., Rajasthan, Uttar Pradesh) and the USA (e.g., Arizona, Nevada, Tennessee).
 * **Manual expansion**:
 If [AllowClusterExpand](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Maps.MapsMarkerClusterSettings.html#Syncfusion_Blazor_Maps_MapsMarkerClusterSettings_AllowClusterExpand) property is set to **true**, a user can click a cluster to expand it immediately and view its child markers without additional zooming. This is useful on touch devices or when you want quick access to the underlying points.
 * **Per‑group customization**:
