This visualization displays a hierarchical tree of Airbnb listings in New York City, organized by room type, borough, and neighborhood, with node labels sized by depth. It uses d3.tree and d3.hierarchy to compute the layout, d3.linkHorizontal for curved link paths, and d3.zoom for panning and scaling the SVG. The data comes from a JSON file containing house counts and average prices. Text shadows and a serif font improve readability, while node positions reflect the tree structure rather than geographic location.
