What are the options available for viewing clusters?

The correct option for viewing clusters is Circle Pack. This visualization method is particularly effective in representing hierarchical data as circles, where each circle can encompass smaller circles, effectively showing the relationships between different clusters. Circle Pack allows users to quickly comprehend the size and hierarchy of clusters while also gaining insights into the composition of each cluster through the size and arrangement of the connected circles. This makes it a powerful tool for visualizing and exploring clusters in a dataset, especially in scenarios where understanding group relationships and sizes is crucial.

Other options, while they might suggest different visualization techniques, do not specifically represent clusters as effectively as Circle Pack. Dial Visualization and Cluster Wheel may focus on different aspects of data representation or use other forms of visualization that do not inherently emphasize the cluster relationships as clearly. Nearby Clusters might imply a spatial or geographical context to clusters, which does not inherently provide a comprehensive visualization on its own compared to the Circle Pack's cohesive representation of hierarchical clustering.
