{"version":"1.0","type":"rich","title":"hw2","description":"This animated parallel coordinates plot displays the Iris dataset with four quantitative axes (sepal length/width, petal length/width) and one categorical axis (species). Lines show each flower’s measurements, colored by species using `d3.scaleOrdinal` with `schemeCategory10`. Users brush along any axis via `d3.brushY`, filtering lines dynamically with opacity transitions using `transition().duration(500)`. The code imports from `d3` and `d3-rosetta` for reusable rendering, resizing via `observeResize`, and memoization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aab3c0258ffb408e8466e63f0357fc26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
