What element of art is described as a point moving across space?

The element of art described as a point moving across space is line. A line is essentially a continuous mark made on a surface that has length but typically not significant width. It can be straight or curved, thick or thin, and is fundamental in creating shapes, patterns, and forms within a composition. Lines can guide the viewer's eye, create texture, and convey movement or energy in a work of art. This understanding of line is crucial, as it serves as the building block for many other elements of art, influencing how shapes and forms are perceived.
