A line in design can serve various purposes such as defining boundaries, creating hierarchy, adding movement, and directing the eye of the viewer. Lines can be used to separate different elements in a composition or to connect them, and can be straight, curved, dashed, or textured to convey different moods or feelings. In addition, lines can also be used to emphasize certain parts of a design, create patterns, or lead the viewer's gaze towards a focal point. Overall, lines play a crucial role in design by helping to organize and structure visual elements to communicate a clear and effective message.
