This example shows a horizontal bar chart of 2010 population estimates for select countries, with green bars sorted by country name and labeled axes. Built with React and D3 v5, it uses `scaleBand` and `scaleLinear` to position bars, `csv` to load data from a GitHub-hosted CSV file, and SVG `rect` elements to render marks. The code defines reusable Axis and Marks components, formats tick labels with `format`, and includes a tooltip title on each bar showing the population value.
