A horizontal bar chart displays the top 10 countries by population in the year 2000, using red bars sorted in descending order. The visualization is built with React and D3 v7, rendering as SVG via ReactDOM. It employs d3.scaleLinear for the x-axis and d3.scaleBand for the y-axis, with population data parsed from a CSV file fetched via d3.csvParse and fallback sample data.
