Which principle focuses on creating a pathway for user navigation?

The principle that focuses on creating a pathway for user navigation is movement. This concept refers to guiding users' attention through a design or layout in a way that helps them navigate seamlessly from one part of the content to another. Effective use of movement can involve visual cues like arrows, lines, or the arrangement of elements that lead the viewer’s eye in a specific direction. This is essential in web design because it helps users find important information quickly and intuitively, enhancing their overall experience.

In this context, while rhythm, emphasis, and unity are important design principles, they do not primarily address the navigational aspect. Rhythm relates to the repetition of elements to create a sense of organized movement, emphasis focuses on highlighting certain elements to draw attention, and unity is concerned with how well various parts of the design work together as a cohesive whole. None of these principles manage the navigation pathway as directly as movement does.
