A fork of the classic parallel coordinates example displays leaf shape measurements from a CSV dataset across multiple numeric axes, with each of the three leaf classes drawn as a colored line (blue, yellow, red) and a legend identifying the classes. Users can drag axis labels to reorder dimensions, triggering animated transitions of the polylines. The visualization is built with D3 v3 using `d3.svg.line` for the paths, `d3.svg.axis`, ordinal and linear scales, and `d3.behavior.drag` for interactive axis reordering. A legend, rendered manually with SVG circles and text, indicates the class colors.
