A static line chart traces each of ten countries’ CO₂ emissions against temperature anomaly over time, while animated dots and a year label play through the timeline. The visualization uses d3.csv, d3.scaleLinear, d3.line, and d3.schemeTableau10 to render SVG paths and circles, with d3.axisBottom and d3.axisLeft for axes. Animated dots update their positions each year via d3’s selection and transition methods, showing how each nation’s climate trail evolves. The data comes from a GitHub Gist, and the rendering uses SVG with CSS styling for opacity and stroke width.
