shape: This defines how the coords are interpreted. Possible values are:; rect, circle, poly
coords: Rectangles are specified using x1,y1,x2,y2 where x1=left, y1=top, x2=right, y2=bottom.; Circles are specified using x,y,radius where x/y is the center point.; Polygons are specified using any number of x/y pairs x1,y1,x2,y2,..,xn,yn

Examples
