This bar chart displays the 2020 population estimates for the 30 most populous countries, sorted by country name. The visualization uses React to render SVG elements, with D3 v5 scales (`scaleBand`, `scaleLinear`) and formatting (`format`) handling the layout and tick labels. Population values are loaded from a remote CSV file and multiplied by 1000. The chart includes custom axis components and green bars with tooltips showing formatted population values.
