This bar chart displays the population of the top ten most populated countries using 2018 estimates from the United Nations World Population Prospects. It encodes country names on the y-axis with a d3.scaleBand and population values on the x-axis with a d3.scaleLinear, rendering rectangles in SVG. The visualization uses d3.axisLeft and d3.axisBottom for the value labels and applies a hover effect that changes rectangle fill via CSS. Data is loaded through d3.csv and parsed as numbers before being mapped to the scales.
