CoClasses that implement IGraphicCallout

CoClasses and Classes Description
FEGraphic A cached graphic that symbolizes a point based military object (feature or force element).
GraphicLeader A collection of leaderable cached graphics, sorted and drawn using a variety of leader styles, designed to help declutter a display.
GraphicStack An ordered collection of stackable cached graphics, drawn to resemble a stack of cards.

Remarks

Cached graphics don't always need to draw on top of their base geometry.  Sometimes it is desirable to darw them offset from their actual location.  An anchor point provides a called out graphic with this alternate drawing location.  A line can also be drawn between a graphic's actual location and its drawn location.
