Which of the following is NOT considered a key principle of graphic design?

Focus is not traditionally considered a key principle of graphic design in the same way that contrast, movement, and unity are.

Contrast involves the use of opposing elements, such as color and size, to create visual interest and highlight important aspects of the design. It helps make certain elements stand out and catches the viewer's attention.

Movement pertains to the way the viewer's eye is directed through the design. It encompasses the arrangement of elements to guide the observer's gaze and create a dynamic experience. Understanding movement is essential for creating effective visual storytelling.

Unity refers to the cohesion of all elements within a design. It ensures that all parts work together harmoniously, creating a consistent look and feel. Unity helps in conveying the intended message effectively as it binds all elements into a coherent whole.

While focus is important in the context of guiding viewers to key messages or elements, it does not hold the same foundational significance as the other principles, which serve as basic guidelines for creating compelling and effective graphic designs.
