This bar chart displays the population of ten countries in the year 2000, with a green horizontal bar for each country, ordered from largest to smallest population. The visualization uses React to render SVG elements via d3.scaleBand and d3.scaleLinear, and reads CSV data from a GitHub repository. Population values are formatted using d3.format with SI notation. A native SVG `<title>` element provides a tooltip showing the exact population value for each bar.
