This tree visualization displays a hierarchical taxonomy of ArcGIS point-of-interest categories, branching from broad top-level groups like “Food” and “Travel and Transport” into detailed subcategories. The layout uses d3.tree() with linkHorizontal to position and connect nodes, rendering text labels at varying font sizes by depth. Implemented with d3.v5 and SVG, the view supports zooming via d3.zoom(). Data comes from data.csv, listing parent categories and their newline-separated children.
