This bar chart displays the population of the ten most populous countries, with horizontal bars sorted by country name. The visualization uses D3 v5 to load data from a CSV file, scale the population values linearly, and render the chart as an SVG. The code applies `scaleBand` for the categorical country axis and `scaleLinear` for the population axis, while `axisLeft` and `axisBottom` generate the tick marks and labels. Bars are drawn as SVG rectangles with a steelblue fill, and the chart includes margins and a rescaled population axis.
