This animated area chart displays renewable energy generation trends for the USA from 2010 to 2024, comparing solar, wind, and hydro sources. The visualization uses D3 v7’s `d3.area()` and `d3.line()` generators with `curveMonotoneX` to render semi-transparent filled regions with stroked boundaries, while `d3.axisBottom` and `d3.axisLeft` provide labeled scales. Hover interactions reveal tooltips on data points, and the chart reads from a CSV file containing annual GWh values for multiple countries, though only USA records are visualized.
