A point marks a position in space and graphically takes form as a dot. A series of points form a line.
Lines can have many weights with thickness and texture. They multiply to describe volumes, planes and textures and can be straight, curved, continuous, broken, strong, or insignificant.
Both can be seen everywhere in our everyday lives and through all forms of art. They can impact an audience simply through their position or size.
Together, they give a sense of balance and give the perception of depth.
