This animated scatter plot displays the Iris dataset, cycling through four feature combinations to show relationships between sepal and petal measurements. Three species—setosa, versicolor, and virginica—are color-coded skyblue, lightgreen, and orange, with a legend and axis labels updating as the x-axis changes. Built with D3.js, it uses `scaleLinear`, `axisLeft`, and `axisBottom` for the axes, while a `setInterval` loop updates the x-value binding, redrawing circles and labels. The SVG rendering includes title, rotated axis text, and custom styling from an external CSS file.
