This visualization shows the relative changes in solar, wind, and hydro energy production from 2000 to 2182, with each series represented by a colored line and legend. The React-based code loads a CSV file with d3.csv, then uses d3 scales, axes, and the d3.line generator to render the multi-series chart as an SVG. Gridlines and point markers are added for readability, while D3’s scaleLinear and extent methods determine the axis domains.
