A horizontal bar chart displays the top 20 countries by 2010 population, with green bars ordered by country name along the y-axis and population values on the x-axis. The visualization uses React with D3 v5’s `scaleBand` and `scaleLinear` to position bars and axes, while `csv` loads data from a GitHub-hosted CSV file. Custom React components (`AxisBottom`, `AxisLeft`, `Marks`) render SVG elements, with a Poppins font and formatted tick labels converting billions from D3’s `.2s` format.
