This visualization displays a hierarchical tree of ArcGIS point-of-interest categories, showing parent categories branching into their specific child values. It uses D3 v5’s `tree` layout and `linkHorizontal` generator to position and draw the SVG paths, with text labels scaled by depth. The data is loaded from a CSV file containing parent-child pairs, and the zoom behavior is enabled through `d3.zoom` for interactive panning and scaling.
