This interactive parallel coordinate plot displays the classic Iris dataset, with each flower’s sepal and petal measurements drawn as a polyline across four vertical axes. Lines are colored by species (setosa, versicolor, virginica) and rendered with SVG. Users can drag any axis to reorder the dimensions, with d3.drag handling the interaction and d3.transition animating the axes and paths into their new positions. The code uses d3.scalePoint, d3.scaleLinear, d3.axisLeft, and d3.line to construct the visualization.
