Labels

This GeoBlazor sample, written in Blazor for .NET developers, demonstrates feature labeling from the ArcGIS Maps SDK for JavaScript using GeoBlazor's Label and TextSymbol Razor components. The page shows a 2D web map centered on the Joshua Tree area of southern California, loaded from an ArcGIS Online portal item. Overlaid on top is a FeatureLayer of trail markers, rendered as small dark green circles. Each marker is automatically labeled above its center with the value of the MARKER_ACTIVITY field, drawn in bold green Playfair Display font on a translucent lavender background with a green border. The label text, placement, font, and background styling are all configured declaratively through the Label, TextSymbol, MapFont, and LabelExpressionInfo components. There are no interactive controls — the user simply pans and zooms the map. The sample is intended to demonstrate how to attach data-driven labels to feature layers in a Blazor application without writing JavaScript.
