Clustering Popups
This sample demonstrates how to generate a default PopupTemplate and labels for point clusters enabled in a MapView.
To generate a PopupTemplate, use the injectable PopupTemplateCreator class and the GetTemplates method.
Use the LabelCreator class and the GetLabelSchemes method to generate suggested default labelingInfo
for the clusters along with a suggested clusterMinSize.

About this sample
This GeoBlazor Pro sample, written in Blazor for .NET developers, demonstrates auto-generated cluster popups and labels from the ArcGIS Maps SDK for JavaScript exposed through GeoBlazor Pro's PopupTemplateGenerator and LabelGenerator services together with the FeatureReductionCluster Razor component. The page shows a 2D topographic map centered on India displaying a Places of Worship FeatureLayer aggregated into clusters. An ExpandWidget pinned in the upper-right corner contains a Filter by religion dropdown (All, Hindu, Christian, Muslim, Buddhist, Sikh, Jain), an Enable/Disable Clustering button, and a LegendWidget. Selecting a religion sets a feature filter on the layer view to show only matching places, and toggling clustering swaps the layer between aggregated and raw rendering. Clicking a cluster opens a generated popup describing the dominant attribute mix; clicking a single feature shows its name, religion, and denomination. The sample is intended to demonstrate generator-driven cluster styling with attribute filtering and popups.
