This interactive scatter plot visualizes the Iris dataset, with points colored by species (setosa in yellow, versicolor in black, virginica in red) to show relationships between sepal and petal measurements. The visualization cycles through different variable pairings every two seconds, allowing comparison of petal width, sepal width, petal length, and sepal length. Built with D3 v6, it uses reusable chart functions with scaleLinear, axisLeft, and axisBottom for axes, while a setInterval timer switches the x-axis variable. The SVG renders animated circles with a title and axis labels.
