This bar chart displays the populations of the top 10 most populous countries, using horizontal bars ranked by descending population. The visualization uses D3 v6 with SVG rendering, employing `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft` and `axisBottom` for the axes. Data is loaded from a CSV file and parsed with `csv`, with the chart drawn using `select` and `append` on the SVG container.
