This document discusses the elements of visual composition, including line and shape. It provides definitions of line as the visual path that guides the eye, and shape as the external boundary or outline of an object. The document then shares diagrams from landscape architect John Ormsbee Simonds and illustrator Andrew Loomis that analyze lines and shapes, assigning them descriptive meanings and associations. Simonds' diagram maps 48 different "mood lines" while Loomis describes compositions based on basic forms, letters, and symbols.
