graphics layer

A graphics layer is a client-side layer containing a collection of temporary graphics to display on a map. Graphics layers (and graphics) are created dynamically and are available while the application is running. Unlike a feature layer, which stores only those features that share a geometry type, a graphics layer can store graphics with different geometry types, such as points, polylines, and polygons. Graphics in a graphics layer can also have differing sets of attributes. For example, a graphics layer can contain a point graphic representing a location with one attribute, a line graphic representing a train track with two attributes, and a polygon graphic representing an area boundary with three attributes.
