{"version":"1.0","type":"rich","title":"Fork of Interactive Streamgraph Template in React","description":"This fork of the streamgraph template displays multiple ECG data series as stacked, filled areas over time, with a tooltip that appears on hover to identify each stream. Built with React and D3 v5, it uses `d3.stack` with `stackOffsetSilhouette` and `stackOrderInsideOut` to compute the layout, and `d3.area` with `curveBasis` to generate SVG paths. Data is loaded from a CSV gist via `d3-fetch`’s `csv` function. Hovering changes the opacity of non-highlighted streams, while the tooltip text updates to show the active series key.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a89029b06c714dd2bf46b7164ca86da6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
