A parallel coordinates chart displays the four numeric attributes of the classic Iris dataset, with each flower’s measurements drawn as a polyline across seven vertical axes. The colored lines represent the three species—setosa, versicolor, and virginica—using semi-transparent red, green, and blue strokes. Users can drag the axis labels to reorder dimensions, which triggers an animated transition of the foreground paths. The visualization uses `d3.svg.line`, `d3.svg.axis`, and the `d3.behavior.drag` API for interaction, with CSV data loaded via `d3.csv` and rendered as crisp SVG paths.
