This parallel coordinate plot visualizes the classic Iris dataset, displaying 150 flowers across four morphometric traits. Each colored line represents an individual sample, with distinct hues for the three species: setosa (orange), versicolor (teal), and virginica (purple). The visualization uses D3.js v5 with an SVG renderer, employing `d3.scalePoint` for axis positioning and `d3.scaleLinear` for trait values. Users can drag axis labels to reorder dimensions, triggering a smooth transition animation via D3’s `.transition().duration(300)`. A dropdown selector toggles the y-axis range between a global union (`[0,8]`) and per-dimension self-scaling computed from the data extent.
