A bar chart displays population figures for ten countries, sorted from largest to smallest. The visualization uses D3 v5 with SVG rendering, loading data from a CSV file. The code employs `scaleLinear` for the x-axis, `scaleBand` for categorical y-axis placement, and `axisLeft`/`axisBottom` to draw tick marks. Population values are converted to numbers and multiplied by 1000. Rectangles are appended to a grouped `<g>` element, with widths scaled proportionally and fill color set via CSS to steelblue.
