A stylized bar chart displays the top 11 most populous countries based on United Nations World Population Data 2019. Highlighted bars, colored teal with a Poppins font, extend from the left, with a population axis beneath. The visualization uses D3 v6 scales and formats, including `scaleBand`, `scaleLinear`, and `siFormat`, within a React component. The code renders SVG elements directly, with axes and marks built from custom components that map data to coordinates and include tooltips via `<title>` elements.
