This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between different flower measurements. The plot cycles through four variable combinations on the x-axis every three seconds, while the y-axis remains fixed on sepal length. Built with D3.js version 6.7.0, the visualization uses SVG rendering and animation. The code implements a reusable scatter plot component with configurable scales, axes, and symbol types, following the "Towards Reusable Charts" pattern. The Iris data is loaded from a GitHub gist, with points symbolized by species.
