Why are sigma and pi bonds drawn differently?

At this point, I understand how to draw sigma and pi bonds in a diagram. But why are sigma bonds drawn so that the two areas of electron density overlap, while pi bonds are drawn so that the two areas of electron density are parallel and spaced apart (with a line connecting the two areas)? What does this represent? Why must these two types of bonds be differentiated in this way?
