This bar chart displays population figures for ten countries from a CSV file, using horizontal bars sorted by country name. The visualization is built with D3 v5 and rendered as SVG, employing `scaleLinear` for the population axis and `scaleBand` for categorical spacing. The code loads data via `d3.csv`, transforms population values to numbers, and draws axes with `axisLeft` and `axisBottom`. Bars are appended as rectangles with widths proportional to population, styled with steelblue fills and a custom margin layout.
