A horizontal bar chart displays the 2020 populations of 30 countries, sorted alphabetically by country name, with green bars extending from a blue left axis. The visualization uses React to render SVG elements, with d3.scaleBand for the categorical y-axis and d3.scaleLinear for the quantitative x-axis, formatted using d3.format. Population data is loaded from a CSV file via d3.csv, and hover tooltips reveal exact values through SVG title elements.
