Animated three-line chart showing renewable energy generation trends for the USA from 2010 to 2024, comparing solar, wind, and hydro sources. Built with D3 v7, it renders SVG paths for each energy source with colored lines and data point markers. The visualization uses linear scales for time-series axes, axis generators, and a tooltip for hover interaction. Data comes from country_energy_stats.csv, loaded via d3.csv, with lines drawn using the d3.line path generator.
