This bar chart displays the top 10 most populous countries in 2018, based on estimates from the United Nations World Population Prospects 2017. It uses a horizontal bar layout with population values on the x-axis and country names on the y-axis. The visualization is built with D3 v5, employing `scaleLinear` and `scaleBand` for scales, `axisLeft` and `axisBottom` for axes, and SVG rectangles for bars. Data is loaded from a CSV file, with population values multiplied by 1000.
