This parallel coordinate plot visualizes the classic Iris dataset, with each flower sample drawn as a colored polyline across four axes: petal length, petal width, sepal length, and sepal width. The lines are colored by species (red, green, blue), and hovering over a line highlights all samples of that species while dimming the rest. The axes can be dragged horizontally to reorder dimensions; when dragged past another axis, the two axes swap positions with an animated transition. The visualization uses d3.v4 with d3.line for paths, d3.axisLeft for scales, and d3.drag for interactive axis reordering, rendered as SVG.
