A horizontal bar chart displays the 2000 population estimates for ten countries, sorted by country name along the y-axis and population count along the x-axis. The visualization uses D3 v7’s `d3.scaleLinear` and `d3.scaleBand` to map data, with `d3.axisBottom` and `d3.axisLeft` rendering tick labels, and custom `AxisBottom.js`, `AxisLeft.js`, and `Marks.js` modules drawing light green SVG rectangles for each bar. Data is loaded asynchronously from a remote CSV file via `d3.csv`.
