When symbols have an offset from their position, it's important to still see what the real location is. This can be achieved with callouts:
Callouts are graphics that help users understand where a label or a symbol (usually a point) is located on the map, when the symbols have an offset from their initial position.
Callout3D is the base class for classes that add a callout visualization when a
PointSymbol3D or a
LabelSymbol3D has an offset (for example a verticalOffset).
Currently only callouts of type
line are supported. See LineCallout3D.
