Animated scatter plot of the Iris dataset cycles through four feature combinations, using petal width, sepal width, petal length, and sepal length on the x-axis while keeping sepal length on the y-axis. Points are colored by species (setosa, versicolor, virginica) with a legend and axis labels. The visualization uses a reusable scatter plot module built on D3 scales and axes, updating via `setInterval`. Data is loaded from a CSV file, rendered as SVG circles, and includes dynamic axis titles and a title.
