This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5 with an SVG rendering, employing `scaleLinear` for the x-axis and `scaleBand` for the y-axis. Data is loaded from a CSV file and multiplied by 1000 to represent actual population counts. The chart includes axes generated by `axisLeft` and `axisBottom`, with black rectangles representing each country’s population.
