This interactive parallel coordinate plot visualizes the classic Iris dataset, showing how sepal and petal measurements vary across three species of iris flowers. Users can click and drag any vertical axis to reorder the axes, which instantly updates the polyline paths that trace each flower’s characteristics. The visualization is built with D3 v5, using `d3.scalePoint` and `d3.scaleLinear` for positioning, while `d3.drag` handles the interactive reordering with smooth transitions. Species are distinguished by color through custom path strokes, and axis labels plus a legend clarify the data.
