This interactive streamgraph visualizes global CO2 emissions from 1790 onward, with stacked layers representing fossil fuel sources—Solids, Liquids, Gas, Cement Production, and Gas Flaring—in gigatons per year. Using d3.stack and d3.area with a basis curve, it renders smooth, colored bands scaled by a time axis and a linear y-axis. Labels are positioned via d3-area-label’s `d3.areaLabel` function, while tooltips appear on hover. The chart uses d3-scale-chromatic’s `schemeDark2` for colors and reads CSV data, updating responsively on window resize.
