This activity allows you to update an existing graphics layer or create the layer if it does not already exist. You can provide new features to add to the layer and optionally clear any existing features. You can also assign a renderer to control the symbology of the layer.
In a Workflow:
You would use this activity to create a persistent layer in a viewer application that contains custom features and rendering. For example, you could use a Query Task activity to obtain a FeatureSet, then use this activity to create a new graphics layer that contains these features with the symbology of your choosing.
