Line. As a point moves, its path becomes a line. A line has length but no breadth. It has position and direction. It is bound by points. It forms the border of a plane. [Wong, Wucius. Principals of Two-Dimensional Design. New York: Van Nostrand Reinhold Company, 1972.]
Point, line, and plane are conceptual elements that are not visible. Thus when visible, they become form. A line on paper, however small, must have shape, size, color, and texture if it is meant to be seen. So must a point or the plane. Volume remains illusory in two-dimensional design. [Wong, Wucius. Principals of Two-Dimensional Design. New York: Van Nostrand Reinhold Company, 1972.]
