This example visualizes projected carbon emission reductions based on renewable energy prices, comparing CO2 emissions (in billion metric tons) against fossil fuel electricity generation (in trillion kilowatt-hours) over time. The chart uses two separate line series rendered with d3.line and curveNatural, with React components for axes (AxisBottom, AxisSide) and data loading via useEffect and csv. The visualization displays both metrics on a shared time scale, sourced from the US Energy Information Administration, with the chart rendered as SVG in a React application.
