This bar chart displays population figures for ten countries, using horizontal bars sorted from largest to smallest. The visualization employs D3 v6 with SVG rendering, using `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft`/`axisBottom` for the axes. Population data from a CSV file is loaded and converted to numeric values, while rectangles are appended to the chart with heights determined by the band scale’s bandwidth.
