This fork of the Air Quality Dataset Project visualizes New York City community district boundaries and air quality data using D3 v7 with SVG and animation. The map renders GeoJSON polygons representing Manhattan districts, with each district’s geometry colored or encoded to reflect associated air-quality metrics. Built with D3’s geographic projection and path generators, the visualization animates transitions—likely between different pollutants or time periods—while preserving the geographic context. Hover effects and smooth updates support interactive comparison across districts, and the MIT-licensed code provides a reusable template for community-level environmental data exploration.
