This bar chart displays population data for top countries from the 2018 UN World Population Prospects. The visualization uses d3.csv to load data, d3.scaleLinear for the x-axis, and d3.scaleBand for categorizing countries on the y-axis. Population values are multiplied by 1000 to reflect actual counts. The SVG rendering includes d3.axisLeft and d3.axisBottom for labeled axes, with steelblue rectangles representing each country's population.
