This bar chart displays the ten most populous countries, ranked by population with India and China leading. Each bar is color-coded by population size, and a country flag image appears at the end of every bar. The chart loads population data from a CSV file and uses D3 v5 scales, axes, and SVG rendering. Flags are fetched from flagcdn.com, while axis labels and tick formatting are handled through D3’s `scaleLinear`, `scaleBand`, and `format` utilities.
