This bar chart displays the populations of the top 10 most populous countries, based on 2018 estimates from World Population Prospects. The chart uses a horizontal layout with a linear scale for population values and a band scale for country names. The visualization is built with D3 v6, using `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data and render SVG rectangles. Each bar’s length reflects population in thousands, with steel-blue fills and labeled axes.
