Fork of Fork of Fork of Iris Parallel Coordinate Plot
This visualization displays the classic Iris dataset using an interactive parallel coordinate plot, with each of the four traits (sepal length, sepal width, petal length, petal width) mapped to a vertical axis. Users can drag the axes to reorder them, and a dropdown menu toggles the y-axis scale between a fixed union range (0–8) and a per-axis self range based on observed data extents. The plot renders as SVG paths colored by species (setosa, versicolor, virginica) with opacity, and the code uses d3.scalePoint, d3.scaleLinear, d3.axisLeft, d3.drag, and d3.transition to handle layout, interaction, and animated updates.
