A horizontal bar chart displays population estimates for the ten most populous countries, with values scaled in thousands and bars ordered by descending population. The visualization uses D3 v5, loading data from a CSV and rendering to SVG with `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft`/`axisBottom` for ticks. Bars are drawn as `rect` elements, filled with steelblue, within left and top margins.
