A horizontal bar chart displays the population of the top 10 countries in the year 2000, using a linear scale for population values and a band scale for country names. The visualization is built with React and D3 v5, rendering SVG elements through reusable components for axes and marks. Data is loaded from a remote CSV file using D3’s `csv` function and formatted with the `format` utility. Each bar includes a tooltip showing the population value via a native SVG `<title>` element.
