CIRC (Draw a Circle, Arc or Wedge)

Draws a circle, arc or wedge on the map by specifying the center of the circle, radius and enclosing angles. The center of the circle can be joined to the start and stop points on the circle to produce a wedge. The circle will be filled with colour if a fill colour is defined in the attribute used.
