This animated scatter plot visualizes the Iris dataset, cycling through four different variable pairs (petal width, sepal width, petal length, sepal length) every two seconds. Each point encodes species via color, while the initial rendering uses rectangles with varying rx and ry values rather than uniform circles. Built with D3.js, the visualization uses scaleLinear, scaleOrdinal, axisLeft, and axisBottom within a reusable scatterPlot function. The animation is driven by setInterval, while data loading relies on d3.csv. SVG rendering updates axes and marks dynamically as the selected dimensions change.
