This area chart visualizes nuclear energy usage from 2010 to 2020, with a red line showing the trend and an indigo-filled area beneath it. Time is mapped on the x-axis and nuclear values on the y-axis, using D3 v5 with scaleTime, scaleLinear, axisBottom, and axisLeft. The line and area paths are generated with d3.line and d3.area using curveBasis for smoothing, while CSV data is loaded and parsed via d3.csv and d3.timeParse. Grid lines and styled axis labels enhance readability.
