- A graphics overlay is a client-side, temporary container of graphics to display on a map view or scene view. Graphics overlays (and the graphics they contain) are created dynamically and are available only while the application is running. Unlike a feature layer, which stores only those features that share a geometry type, a graphics overlay can store graphics with differing geometry types, such as a combination of points, lines, and polygons. Graphics in a graphics overlay can also have differing sets of attributes. For example, a graphics overlay 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.
