This bar chart visualizes population data for ten countries, with China and India leading by a significant margin. The chart uses D3 v5 to load data from a CSV file via the `csv` method, converting population values to absolute numbers by multiplying by 1000. Rectangles are appended to an SVG container, with the rendering approach relying on D3’s data join to bind the imported dataset. The layout is minimal, with the browser margins removed via styles.css for a full-bleed display.
