This interactive scatter plot visualizes the Iris dataset, coloring points by species and using different symbols to represent each variety. Built with D3 v6, it renders SVG shapes using `d3.symbol` and `d3.scaleOrdinal`. The visualization cycles through four attribute pairings every two seconds via `setInterval`, updating the x-axis mapping and re-calling the reusable chart function. The plot includes labeled axes, a title, and applies a custom color scheme for setosa, versicolor, and virginica flowers.
