This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The code loads data from a CSV and renders circles positioned by a linear scale for population and a point scale for country names. It uses d3.scaleLinear, d3.scalePoint, d3.axisLeft, and d3.axisBottom, with a custom margin and tick formatting. The SVG output includes labeled axes and a title.
