This document discusses the basic elements of visual language, focusing on lines. It defines a line and describes its characteristics like shape, thickness, color, and texture. Lines are classified as simple, composed, zig zag, wavy, curly, scribble/doodle, or dashed. The direction, intensity and variations in a line's direction impact its psychological and expressive qualities. Horizontal lines express peace, vertical lines express strength, and oblique lines transmit instability and movement. Curved lines give a sense of movement and dynamism. Lines can be used to divide space, create textures, and produce shading through hatching. An exercise is described using lines to create a drawing without lifting the pencil.
