Hierarchical data Support

When hierarchy data (e.g., Dates) are added to the chart, they are presented as a Hierarchy, featuring an icon that allows users to expand or collapse the hierarchy. By default, the data is displayed in an expanded state within the visual.

1. The top level of the hierarchy includes an expand/collapse icon located at the right corner of the panel, represented by arrow marks.

2. Clicking the collapse icon condenses the hierarchy into a single panel, displaying only the hierarchy heading. In this view item cannot be selected.

3. Clicking the expand option unfolds the hierarchy, revealing all levels as separate panels. In this view items can be selected from the panel shown.
