This example displays the classic Iris dataset in a parallel coordinate plot, with each of the four floral measurements mapped to vertical axes and individual flowers drawn as colored polylines—red for setosa, green for versicolor, and blue for virginica. The visualization uses D3 v5 with SVG rendering, employing `d3.scalePoint` for horizontal axis placement and `d3.scaleLinear` for vertical scaling. Users can drag any axis horizontally via `d3.drag` to reorder dimensions and explore correlations between variables. Data comes from the bundled `iris.csv` file, and the code also renders axis labels and a legend.
