This example displays a horizontal bar chart of the top 10 most populous countries in 2019, sourced from a CSV file. The visualization renders the chart as an SVG, using React for component structure and state management, while D3 v5 utilities like `scaleBand`, `scaleLinear`, and `csv` handle data loading and scaling. The code draws axis ticks and labels directly, alongside the bars, within a single SVG `<g>` element.
