This interactive parallel coordinates plot visualizes the Iris flower dataset, displaying four measured attributes (sepal length/width, petal length/width) as parallel axes. Each of the 150 flower samples appears as a polyline, colored by species using a D3 ordinal scale mapping to purple, gray, and blue. Users can drag axis labels to reorder dimensions, which triggers animated transitions via D3’s drag behavior and transition methods, while the foreground and background paths update dynamically. The visualization uses D3 v3’s SVG rendering, with custom axes and brushing support for data exploration.
