This simple stacked area chart visualizes the growth of global installed energy capacity (Solar, Wind, Hydro, and Nuclear, in GW) from 2000 to 2022, highlighting that all categories rise over the period. The chart uses the D3.js library version 7, reading data from a CSV file and rendering to SVG. It constructs the visualization using `d3.stack()` and `d3.stackOffsetNone` to compute the layers, `d3.curveMonotoneX` for smooth area interpolation, and standard D3 scales, axes, and gridlines; a legend identifies each energy source.
