This visualization shows crime rates across Indian states and union territories using an interactive choropleth map, with a sidebar providing a color legend and details about the hovered region. It combines D3.js version 6 for data parsing and SVG path generation via `d3.geoPath` with a custom `d3.geoTransform` projection, and Leaflet 1.7.1 for map rendering and interaction. The map loads state boundaries from a GeoJSON URL and colors each polygon based on crime rates from a CSV file using a sequential `d3.scaleSequential` with the `d3.interpolateYlOrRd` color scheme.
