This visualization displays the ArcGIS Supported Category Values as a horizontal tree layout, grouping points of interest into broad categories like Food, Education, and Shops and Service. Each category branches into its individual leaf nodes, with text size and position encoding hierarchy depth. The code uses d3.csv to load the data, d3.tree and d3.hierarchy for layout, and d3.linkHorizontal for edge paths, all rendered as SVG within a zoomable group that leverages d3.zoom.
