{"version":"1.0","type":"rich","title":"ICE7.4","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/31c5c45fce7946b0a5767594152058a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
