This example shows a horizontal bar chart of the top ten most populous countries, with populations scaled to thousands and formatted with abbreviations (e.g., "1.41B"). The chart uses D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the categorical y-axis, with axes rendered via `axisLeft` and `axisBottom`. Data is loaded from a CSV file using `csv()`, and the rendering employs D3’s enter/update/exit pattern to append SVG rectangles. Axis tick lines and domains are styled via CSS.
