This bar chart displays the population of the top 10 most populous countries using 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis and `scaleBand` for the y-axis. Country names appear on the left axis, with population values on the bottom axis. The code reads data from a CSV file, multiplies population values by 1000, and renders steel-blue rectangles using `selectAll('rect').data().enter().append()`.
