This area chart visualizes carbon emissions over time, comparing liquid fuel and gas fuel consumption across multiple years. The data is loaded from a remote CSV file using d3.csv, with parsed numeric values for both fuel types. The visualization uses d3.area generators to create two semi-transparent filled regions, with steelblue representing liquid fuel and orange representing gas fuel. The chart includes linear scales for both axes, axis labels, and a legend, all rendered as SVG elements within an 800x400 pixel canvas.
