This animated scatter plot cycles through four pairwise comparisons of iris flower measurements (petal width, sepal width, petal length, and sepal length) on the x-axis, using the D3.js library. It displays the classic Iris dataset fetched from a GitHub gist, rendering each flower as a circle colored by species (setosa in skyblue, versicolor in lightgreen, and virginica in orange). The visualization also includes a legend and dynamic axis labels, updating at intervals to explore correlations between different feature combinations.
