This stylized bar chart visualizes the top 10 most populous countries using data from the United Nations World Population Prospects 2019. Horizontal bars extend from the left axis, colored teal with a clean, minimal design. The React-based implementation uses D3’s `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and the `format` function to abbreviate population values (e.g., “1.4B”). SVG rendering includes custom React components for axes and marks, with simple tooltips provided via SVG `<title>` elements.
