This bar chart visualization displays population data for ten countries, with horizontal bars representing each nation’s population in thousands. The chart uses D3 v5’s `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft` and `axisBottom` to render axes. Data is loaded asynchronously from a CSV file via `d3.csv` and converted to numbers. The SVG rendering is structured with margins, and bars are appended as `rect` elements with steelblue fill.
