What is the purpose of the hierarchy pane in a tree map?

The hierarchy pane in a tree map primarily serves the function of displaying configured hierarchies, which allows users to drill down into more specific data levels. This feature is essential in data visualization tools because it enables users to understand complex datasets by exploring their structure and relationships.

When users interact with a tree map, they can click on different sections to navigate through hierarchical levels of data, which helps reveal insights that may not be immediately visible in the overall summary view. This drilling down process aids in analyzing specific categories or segments within the broader dataset, facilitating a more detailed examination of the information presented.

Having the hierarchy available enhances the usability of the tree map by providing context and making it easier for users to identify patterns or anomalies within their data as they navigate through different layers of information.
