This visualization combines Leaflet and D3 to display geographic data on an interactive Esri World Imagery map. It uses Leaflet’s tile layer and SVG overlay, with D3’s geoPath and a custom geoTransform projection to render polygon and MultiLineString features from embedded GeoJSON data. The map shows hand-drawn lane boundaries and pincode areas, with polygons that respond to mouseover by changing color. The plot also includes a separate circles.json file containing coordinate points, though these are not referenced in the main HTML script.
