This bar chart displays CO₂ emissions by country for 2025, ranking nations from highest to lowest emissions. Each bar’s length encodes emission values in megatons, while color distinguishes geographic regions through a scaleOrdinal. The visualization uses d3.csv to load remote data, d3.scaleBand and d3.scaleLinear for positioning, and includes hover tooltips showing country, region, and precise values. Animated bar transitions grow from the baseline, and the SVG rendering includes axis labels and an interactive legend.
