This example shows an interactive parallel coordinate plot of the Iris dataset, where users can reorder the four displayed axes (sepal length/width, petal length/width) via dropdown menus. Each of the 150 flowers is drawn as a semi-transparent polylined path, colored by species (setosa, versicolor, virginica). The visualization uses React and D3 v5, employing `scalePoint` for axis positioning, `scaleLinear` for value mapping, and `axisLeft` to render tick marks. A static legend distinguishes the three species, while SVG rendering handles all drawing.
