This bar chart displays the populations of the ten most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization uses a horizontal layout, with the population scale set as a `scaleLinear` and country names mapped to a `scaleBand`. The chart is rendered as SVG. The code leverages D3’s `axisLeft` and `axisBottom` to create the axes, and the `rect` elements are styled with a green fill via CSS. Data is loaded from a CSV file with the `csv` function.
