This interactive parallel coordinates plot uses the classic Iris dataset, displaying each flower as a polyline across four quantitative dimensions (sepal length/width and petal length/width with a fixed 0–8 scale). Each species is color-coded via a D3 ordinal scale. Users can drag axis labels to reorder dimensions, and brush any axis to filter foreground lines. Built with D3 v3, it uses SVG paths for rendering, with animation for smooth transitions during axis reordering.
