This parallel coordinate plot visualizes the Iris dataset, showing measurements of sepal and petal length and width for three flower species. Colored polylines represent individual samples, with red, green, and blue distinguishing Iris-setosa, versicolor, and virginica. Users can click and drag axis titles to reorder dimensions, and hovering a line highlights all samples of that species while dimming others. The visualization uses D3 v5 with SVG rendering and transitions, constructing axes with `d3.axisLeft` and enabling drag behavior via `d3.drag`.
