This interactive parallel coordinates plot visualizes the Iris dataset, with each line representing a flower and colored by species (setosa, versicolor, or virginica) using a D3 ordinal color scale. The graphic displays four numerical dimensions—sepal and petal length and width—on vertical axes, and supports dragging axes to reorder them and brushing along axes to filter the highlighted foreground lines. Built with D3 v3, the SVG rendering includes background and foreground path layers, with axes and brushes appended to each dimension group. The legend uses colored circles to map species to the purple, green, and yellow palette.
