Parallel Coordinate Plots
This interactive parallel coordinate plot visualizes the Iris flower dataset, showing four numeric traits (sepal length, sepal width, petal length, petal width) for three species, each drawn as a colored polyline. Users can drag any axis to reorder the dimensions, with the lines and axes animating smoothly during the transition. The visualization is built with D3 v5, using `d3.scalePoint` for axis positioning, `d3.axisLeft` for each dimension, and `d3.drag` for interactive reordering, rendered as SVG paths with a fade-in transition.
