Cheap tricks for interactive maps - India
This interactive map visualizes India’s districts and states, with each district colored by its state and districts that reveal their name and state on hover. The map supports pan and zoom through d3.zoom, and uses d3.geoMercator with a clip extent for projection. Built with React and D3, it renders SVG paths generated by d3.geoPath from TopoJSON data for states and districts, with district metadata from the Datameet boundary dataset and state names from the deldersveld TopoJSON source.
