This visualization displays a map of New York City's five boroughs with individual crash points from 2025 overlaid as small black circles. The map uses d3.geoMercator and d3.geoPath to render TopoJSON-converted GeoJSON borough boundaries, colored distinctly via a React legend. Crash coordinates from the NYC Motor Vehicle Collisions CSV are projected onto the map. The visualization is built with React, d3.v7, and renders to SVG, with responsive sizing and crash data loaded via a custom React hook.
