This example displays a horizontal bar chart of Indian population data by year, using React to render SVG elements. D3’s `scaleLinear` maps population counts to bar widths, while `scaleBand` positions bars along the y-axis and `scaleOrdinal` assigns colors from `schemeDark2`. The code fetches CSV data via D3’s `csv` method, parses the first five entries, and draws axes with SVG lines and ticks. Both D3 v7 and React 18.2 are used, with the visualization mounted through `ReactDOM.createRoot`.
