{"version":"1.0","type":"rich","title":"Interactive Color Legend","description":"A scatter plot of the Iris dataset maps petal length and sepal width, with points colored by species. The interactive color legend uses React state to track a hovered species, which fades all non-matching marks via `opacity` and re-renders the filtered subset. Built with React, D3 v5 scales (`scaleLinear`, `scaleOrdinal`), and SVG circles, it updates through `MouseEnter` and `MouseOut` events on legend items.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f4d22fb0cd04c66bf680b9471d8530b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
