This bar chart displays the populations of the ten most populous countries, using 2018 estimates from the United Nations’ World Population Prospects. The visualization loads data from a CSV file with `d3.csv`, then renders horizontal bars using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis categories. Axes are drawn with `d3.axisLeft` and `d3.axisBottom`, while each rectangle’s width and height are set by the scales. The chart is rendered as SVG, with bars styled through a CSS `fill` rule.
