This bar chart displays the population of the top ten most populous countries, using horizontal bars ordered from largest to smallest. The visualization loads data from a CSV file with D3 v5, then uses `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft` and `axisBottom` to render the axes. Rectangles are appended to an SVG container, with their widths scaled proportionally to population values.
