This area chart visualizes U.S. nuclear capacity in megawatts over time, sourced from a CSV file. The chart uses an SVG rendering with an aquamarine fill and slateblue stroke, created with D3 v4 within a React framework. The code loads data via `d3.csv`, parses dates with `d3.timeParse`, and constructs the area using `d3.area` with scaled axes from `d3.scaleTime` and `d3.scaleLinear`. Axis labels for "Date" and "U.S. Nuclear Capacity" are added via SVG text elements.
