A bar chart displays the top 15 most populous Indian states, ranked by basic cost. The visualization uses React to manage state and render SVG elements, while D3.js provides scales, axes, and data loading via `d3.csv`. The horizontal bars are drawn with SVG `rect` elements, with axes generated using `d3.scaleBand` and `d3.scaleLinear`. Data is fetched from a remote CSV file hosted on GitHub, styled with explicit margins and a loading state.
