This example visualizes the Iris data set using parallel coordinates, with each flower variety rendered in a distinct color to show its attribute patterns. The view allows users to drag axis labels to reorder dimensions and rearrange the corresponding polylines. The implementation uses D3 v3 with SVG rendering, building ordinal and linear scales for axes and color, and applying `d3.behavior.drag` for interaction. Background lines provide context, while an animated transition repositions axes and paths after dragging.
