This animated scatter plot cycles through four Iris flower measurements, showing petal length, petal width, sepal length, and sepal width on both axes. The visualization uses D3.js to render SVG circles colored by species, with a legend and rotating axis labels. Data comes from a CSV file loaded via `d3.csv`, and the plot updates every few seconds using `setInterval` to change which measurement is displayed, creating a looping exploration of the dataset.
