India Geometries displays two adjacent maps of India's districts, rendered from TopoJSON files processed with MapShaper. The maps are drawn using the `d3.geoPath` function, which interprets the topology data to create vector shapes. A slider or control appears to switch between the full and simplified geometries, demonstrating the visual difference in detail. The code loads the geographic data from the provided JSON files and uses D3's projection and path generation to visualize the country's administrative boundaries.
