In Dial Visualization, what do the secondary, tertiary, and quaternary rings represent?

In Dial Visualization, the design is structured to represent hierarchical relationships between clusters. The primary cluster is typically at the center, serving as the focal point. As we move outward, the secondary, tertiary, and quaternary rings demonstrate the progressively subordinate clusters related to the primary one. The secondary ring encompasses child clusters directly associated with the primary cluster, while the tertiary and quaternary rings continue to represent further sub-relationships.

This organization allows users to intuitively grasp how different data sets relate to one another, enhancing clarity and comprehension. The outer rings signify the depth of hierarchy in a visually segmented manner, making it easier to analyze the structural connections without the clutter of irrelevant information. Therefore, understanding that these rings represent child clusters of the primary cluster is critical for effectively interpreting the visual data structure.
