This bar chart displays population figures for the ten most populous countries, using horizontal bars ranked from largest to smallest. The visualization loads data from a CSV file and renders it as SVG rectangles via D3 v5, with populations scaled linearly along the x-axis and countries positioned by a band scale on the y-axis. It includes axes generated by `axisBottom` and `axisLeft`, and applies a steelblue fill and font styles from an external CSS file.
