This example demonstrates a reusable scatter plot component built with D3.js and React, visualizing the Iris dataset. The plot cycles through different feature combinations on the x-axis (petal width, sepal width, petal length, sepal length) every few seconds, with animated transitions updating the axes and circles. Points are colored by species (setosa, versicolor, virginica) using a custom color mapping, and a legend displays the species labels alongside their corresponding colors. The visualization uses D3 scales, axes, and SVG rendering, with the reusable `scatterPlot` function managing the plot structure and update logic.
