This interactive map displays the states of India using GeoJSON data from the India State Map Data GitHub repository. Users hover over regions to reveal state names via a tooltip and click to toggle a persistent selection state, visualized by distinct fill colors. The visualization is built with React and D3.js, leveraging `d3.geoMercator` for projection, `d3.geoPath` for geographic paths, and state-based styling to update SVG attributes dynamically. The map loads the geographic data asynchronously and handles loading and error states.
