This visualization displays nuclear energy production over time from 2010 to 2019, combining a smooth line and filled area chart to emphasize both trend and magnitude. The x-axis maps years using d3.scaleTime, while the y-axis uses d3.scaleLinear for energy values. The code employs d3.line, d3.area, and d3.curveBasis to generate the curved shapes, with d3.csv loading the data from a GitHub gist. Red strokes and a sky-blue area fill highlight the changes in nuclear usage across the decade.
