The chart is built using React and D3 v5, combining React state management for hover interactions with D3’s `stack`, `area`, and `curveBasis` functions from the `d3-shape` module. The data, loaded via `d3-fetch`'s `csv` method, is rendered as SVG paths, with a tooltip displayed in the top-left corner.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7de44e554a7b4eac84d0e8e67cd42950?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
