This interactive map visualizes US police shooting incidents, with individual shootings represented as colored dots positioned by latitude and longitude using a d3.geoAlbersUsa projection and d3.geoPath. A dropdown menu allows users to group and color the shootings by categories such as race, gender, or threat level, with a color legend displaying the current category values. The visualization uses React for state management, D3 v5 for geospatial and data processing, and renders as SVG elements. Data is loaded from a CSV file containing police shooting records.
