The Iris Parallel Coordinate Plot visualizes four numeric measurements—sepal length, sepal width, petal length, and petal width—for three iris species, with each polyline colored by class. Users can drag any vertical axis horizontally to reorder dimensions, which dynamically updates the paths and axis positions via d3.drag and transitions. The visualization uses d3.csv to load the Iris dataset, d3.scalePoint and d3.scaleLinear for axes, and renders with SVG paths and circles, including a legend showing the species-to-color mapping.
