This bar chart displays the population of the 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The chart is rendered using D3 v5 and SVG, with length-encoded bars representing each country's population in thousands. The visualization employs D3's `scaleLinear` and `scaleBand` for scales, along with `axisLeft` and `axisBottom` for axes, and includes a title. The data is loaded from a CSV file, and the bars are styled with a steelblue fill.
