A fork of the classic Iris parallel coordinate plot visualizes the Fisher iris dataset across four numeric traits, colored by species. The SVG lines encode each flower's measurements, with draggable y-axes for reordering dimensions. The code uses D3 v5 APIs such as `d3.scalePoint`, `d3.scaleLinear`, `d3.axisLeft`, and `d3.line`, with drag behavior and transitions to animate axis reordering.
