This multi-series line chart visualizes renewable energy production over time, plotting yearly values for solar, wind, and hydro energy sources from a CSV dataset. The chart uses React with D3 v7 to render SVG elements, employing `d3.scaleLinear` for axes, `d3.line` for the path generator, and `d3.axisBottom`/`d3.axisLeft` for ticks. Colored lines distinguish each energy type, with a legend and axis labels clarifying the data.
