Which principle of visual communication involves the organization and relationship between elements?

The principle of visual communication that pertains to the organization and relationship between elements is hierarchy. Hierarchy establishes an arrangement of visual elements in a way that signifies importance, guides the viewer's eye, and helps communicate information effectively.

In design, hierarchy ensures that the most important elements stand out to the viewer, which is often achieved through size, color, contrast, and placement. By effectively using hierarchy, designers can create a visual flow that logically leads viewers through the content, enabling them to grasp the intended message more clearly.

While other principles involve organization and relationships, such as proximity—which focuses on the closeness of elements to imply connections—hierarchy specifically addresses the overall importance and order of elements, making it essential for effective visual communication.
