This map visualization overlays hand-drawn vector features of Worli, Mumbai onto an Esri World Imagery basemap using Leaflet and D3. The code loads GeoJSON data from `lines.js` and `polygon.js` containing road lane polylines and pincode area polygons, rendering them as SVG paths. Geographic coordinates are converted to screen space via `d3.geoTransform` and Leaflet's `map.latLngToLayerPoint` method. Polygons update on zoom events through a zoom handler that recomputes their path geometry.
