This bar chart displays population estimates for the ten most populous countries, with each bar’s length proportional to the country’s population. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map population values to bar widths and country names to vertical positions, rendering bars as SVG rectangles. Data is loaded from a CSV file, and populations are parsed and multiplied by 1000 before rendering. The chart includes fixed margins but no labels, leaving the bars to communicate the ranking.
