The Legend widget displays labels and symbols for layers in the scene. It supports FeatureLayer, SceneLayer, MapImageLayer, and TileLayer. The legend automatically updates when the visibility of a layer or sublayer changes.
Currently 3D symbols with more than one symbol layer are not supported, and the size in volumetric 3D symbols, such as polygon extrusion, is not depicted by the Legend widget. See JSAPI Legend for more information.
