This interactive parallel coordinate plot displays the Iris dataset's four measurements as polylines connecting labeled axes. Users can drag axis labels to reorder variables, while hovering over color-coded legend entries highlights one of three Iris species using D3 transitions. The visualization is built with D3 v5, using scalePoint, scaleLinear, and drag behavior APIs to implement the reordering and highlighting interactions. SVG paths render the data lines, and the axis ordering updates dynamically during drag events.
