The Iris Parallel Coordinate Plot visualizes the classic Iris dataset across four numeric dimensions—sepal length, sepal width, petal length, and petal width—with each flower colored by species. Users can drag any vertical axis horizontally to reorder the dimensions, which dynamically redraws the polylines and axis positions with a 350ms transition. Built with D3 v5, it uses `d3.line` for path generation, `d3.scalePoint` for ordinal axis placement, `d3.drag` for interaction, and an SVG renderer with a legend showing the three Iris species.
