This bar chart displays the population of the ten most populous countries, using horizontal bars ordered alphabetically by country name. The visualization loads data from a CSV file and renders it as SVG rectangles. It uses D3 v5 scales and axes, including `scaleLinear` for the population axis and `scaleBand` for the categorical country axis, with `axisLeft` and `axisBottom` for tick marks. The bars are styled steelblue via an external stylesheet.
