This fork of the classic Iris parallel coordinate plot visualizes four morphological traits of iris flowers across three species, with each line color-coded by species. Users can drag the vertical axes to reorder dimensions and toggle between two y-axis scaling modes: a fixed union range shared across all traits, or a per-axis self range based on each attribute's extent. Built with D3 v5, the visualization uses SVG paths for polylines, d3-drag for interactive axis manipulation, and d3.scalePoint with d3.scaleLinear to map traits and measurements. Data comes from the iris.csv dataset.
