This visualization uses parallel coordinate plots to display the Iris dataset, with each of the four flower measurements (sepal and petal length/width) represented on separate vertical axes. The plot colors each of the 150 observations by species—setosa, versicolor, and virginica—using distinct blue, orange, and purple lines. The code employs D3 v5 functions such as `scalePoint`, `scaleLinear`, `axisLeft`, and `line` to render the SVG paths and axes. Interactive buttons on the right allow users to reorder the axis sequence by selecting and moving individual feature labels.
