This bar chart displays population figures for ten countries, sourced from United Nations data in a CSV file. It encodes country names on the y-axis using `scaleBand` and population values on the x-axis with `scaleLinear`, rendering steelblue rectangles in SVG. The code builds the visualization with d3.csv, axis generators `axisLeft` and `axisBottom`, and margin-based layout, appending a group element to position the chart within the SVG canvas.
