This interactive scatter plot animates through different pairs of Iris flower measurements, cycling petal width, sepal width, petal length, and sepal length on the x-axis while keeping sepal length on the y-axis. Built with React and D3.js (version 6.7), it uses `scaleLinear`, `axisLeft`, `axisBottom`, and `scatterPlot` to render SVG circles colored by species (setosa, versicolor, virginica), with a legend and axis labels. The animation updates every interval via `setInterval`, redrawing the plot with new column selections. Data originates from a CSV of Iris measurements fetched from a GitHub gist.
