This interactive visualization displays India’s administrative divisions, using distinct colors for districts and dark green highlighting on hover. It also marks state boundaries with a black stroke. The map is rendered as SVG using `d3.geoPath` with a Mercator projection, and supports zoom and pan via `d3.zoom`. District and state boundaries come from TopoJSON files, with district names and states shown as tooltips. The code also loads a CSV of Indian cities, though city markers are not rendered.
