A horizontal bar chart displays the top 10 most populous countries, ranked by population with a linear scale for the x-axis and a band scale for the y-axis. The visualization uses d3.csv to load data from a CSV file, converting population values from strings to numbers before rendering. Rectangles represent each country's population, with axis labels and a title added via d3.axisBottom, d3.axisLeft, and SVG text elements. The chart employs d3.scaleLinear and d3.scaleBand for scaling, with margins defining the inner plotting area.
