This interactive parallel coordinates plot visualizes the four measured features (sepal length, sepal width, petal length, petal width) of the classic Iris dataset, with each of the 150 samples represented as a polyline. Lines are colored by species (setosa, versicolor, virginica) using a D3 ordinal scale. Users can drag axis labels to reorder dimensions, triggering smooth transitions via `d3.transition()`. The implementation uses D3.js (`d3.scalePoint`, `d3.drag`) and renders as an SVG with CSS animations, drawing data from a local CSV file.
