This stacked area chart visualizes global CO2 emissions over time, broken down by fossil fuel types. The data is parsed from a CSV file and rendered as an interactive SVG, with each layer representing a distinct emission category. The visualization uses d3.stack() to compute the stacked series and d3.area() to draw the areas. Labels are positioned automatically using the d3-area-label library. Hovering highlights individual segments, and the chart adapts to window resizing, with axes and scales generated via d3.axisBottom and d3.axisLeft.
