This example presents a parallel coordinate plot of the classic Iris flower dataset, coloring each line by species (setosa, versicolor, virginica) to reveal multidimensional patterns. Users can drag the axis labels to reorder dimensions, prompting the bundled polylines to animate smoothly into new positions via `d3.drag()`. Hovering any line highlights its entire species group while dimming others through CSS opacity transitions. The visualization is built with D3 v4, using SVG elements and `d3.line()` to generate the paths from the CSV data.
