This bar chart displays the population of the top 10 most populous countries, sourced from the World Population Prospects 2017 dataset. The visualization uses d3.scaleLinear and d3.scaleBand to map population values and country names to SVG rectangles, with axes formatted via d3.axisLeft and d3.axisBottom. Population numbers are converted from thousands using the d3.format module, and the chart is rendered entirely with SVG elements.
