data GraphOutput Source
data GraphInput Source
Type to express a position on the screen. It uses the format (x,y). As Canvas is used in the example implementation, remember that the lefttop corner is (0,0) and the leftbottom corner is (0, height of screen).
data MouseButton :: *
The MouseButton on the mouse.
