This bar chart displays the populations of the world’s ten most populous countries, based on 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map population values to horizontal bar lengths and country names to vertical positions. Data is loaded from a CSV file via `d3.csv` and rendered as SVG rectangles. The chart includes left and bottom axes generated with `d3.axisLeft` and `d3.axisBottom`.
