This interactive visualization presents the classic Iris dataset as a parallel coordinate plot, with each of the 150 flowers represented as a colored line traversing four parallel axes for sepal and petal lengths and widths. D3.js v6 constructs the chart using `scaleLinear`, `scalePoint`, and `line`, while the React dropdown library loads the dataset. The legend circles classify the three Iris species. Users can hover over any line to highlight all flowers of that class while dimming the others, revealing clustering patterns across the four dimensions.
