This example presents an interactive parallel coordinates plot of the Iris dataset, with each flower species (setosa, versicolor, virginica) colored distinctly in purple, green, or yellow. Users can drag dimension axes to reorder them and use brush controls on each axis to filter the displayed lines. The visualization uses D3.js v3 with SVG rendering, built on a React framework. The code employs d3.svg.axis, d3.behavior.drag, and d3.svg.brush to enable these interactions, while the foreground paths are colored via an ordinal scale mapping species to the viridis color palette.
