This interactive scatter plot animates through different pairings of Iris flower measurements, cycling between petal width, sepal width, petal length, and sepal length on the x-axis while keeping sepal length on the y-axis. The visualization uses the D3.js library loaded via React, rendering points as SVG circles whose colors map to three Iris species. It incorporates a dynamic legend and axis labels that update with each animation frame, driven by D3's `setInterval` and the reusable `scatterPlot` function.
