This bar chart displays the populations of ten countries, with China and India leading in total population. The visualization uses a linear scale for population values on the x-axis and a band scale for country names on the y-axis, rendering bars as SVG rectangles. The code employs d3.csv to load the data, d3.scaleLinear, d3.scaleBand, d3.axisLeft, and d3.axisBottom to construct the scales and axes. Population values are multiplied by 1,000 during data preprocessing, and the chart applies a steelblue fill to the bars.
