This example shows a map of New York City traffic crashes, with each crash represented by a colored circle that indicates the type of severity (injury, fatality, or no injury). The map is built using Mapbox GL JS for the interactive basemap, while D3.js (v3) handles fetching the GeoJSON crash data and styling the circle layer’s color and radius. The circle size scales dynamically with zoom level, and Turf.js is loaded but not used in the visible code. The data comes from the `nyc_crashes.geojson` file hosted on GitHub.
