This bar chart displays the populations of the ten most populous countries, using horizontal bars ordered from largest to smallest. The visualization is built with D3 v7, loading data from a CSV file via `d3.csv` and rendering SVG elements. It employs `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft` and `axisBottom` to generate the axes. Each rectangle’s height is determined by the band scale’s bandwidth, and the fill color is set through CSS.
