This interactive tree visualization displays hierarchical product data, with nodes representing product categories and leaves showing individual items. Users can click nodes to collapse or expand branches, revealing or hiding child elements with animated transitions. The visualization uses D3 v5’s `tree` layout and `linkHorizontal` generator to position nodes and draw curved links, while `zoom` enables panning and scaling. Node rectangles display labels, and the underlying dataset includes KPI metrics like turnover and reference counts, though only the tree structure and labels are rendered visually.
