This interactive scatter plot visualizes the Iris dataset, showing how different flower species cluster across multiple feature combinations. The visualization cycles through three different x-axis measurements—petal width, sepal width, and sepal length—against a fixed y-axis of petal length. Each data point is rendered as a circle colored by species (setosa, versicolor, or virginica), with a legend identifying the categories. The implementation uses D3 v6, including `scaleLinear`, `axisLeft`, `axisBottom`, and a custom reusable `scatterPlot` function that manages the SVG rendering and handles the animation via `setInterval`.
