Fork of Interactive Streamgraph Template in React test 2
This interactive streamgraph visualizes the changing popularity of baby names over time, with each colored stream representing a different name. 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.
