This interactive parallel coordinate plot visualizes the Iris dataset, with each of the 150 flowers represented as a polyline connecting four axes for sepal length, sepal width, petal length, and petal width. Lines are colored by species (setosa, versicolor, virginica) and shown at partial opacity to reveal density patterns. Built with D3 v5 and React, the visualization uses `scalePoint` and `scaleLinear` for axis positioning and y-scaling, while `drag` and `transition` enable users to reorder the axes interactively, with updates handled through the `dragged` and `dragended` callbacks.
