This parallel coordinate plot visualizes the Iris flower dataset, with each line representing a sample and colored by species using a d3.scaleOrdinal. The code uses d3.scaleLinear and d3.scalePoint to position axes for sepal and petal measurements. Users can drag any axis to reorder the dimensions, triggering an event handler that removes and redraws the paths. The SVG rendering relies on d3.axisLeft for axis ticks and labels, with data loaded from the iris.csv file using d3.csv.
