This interactive parallel coordinate plot visualizes the classic Iris dataset, showing how four flower measurements (petal length, petal width, sepal length, sepal width) vary across three species, each colored red, green, or blue. Users can click and drag any axis label to reorder dimensions, with overlapping axes swapping positions automatically. Built with D3 v4, the SVG rendering uses `d3.scaleLinear` for axes, `d3.drag` for interactivity, and hover highlighting via `d3.transition` to dim non-selected lines, emphasizing the species under the cursor.
