A bar chart displays population estimates for ten countries using horizontal bars, sorted from largest to smallest. Built with D3 v5, the visualization uses `d3.csv` to load the data and `scaleLinear` and `scaleBand` for positioning. The SVG renders axis ticks via `axisLeft` and `axisBottom`, with the x-axis formatted to abbreviate numbers, and removes chart gridlines and labels for a cleaner appearance.
