This interactive scatter plot uses the classic Iris dataset to explore relationships between flower measurements, dynamically cycling through different attribute combinations every two seconds. Built with D3.js v6, the visualization leverages reusable chart components like `scaleLinear`, `axisLeft`, and `axisBottom` to render axes and circles via an SVG. The code demonstrates the utility of the `join` pattern for idempotent updates, allowing the plot to smoothly transition between four variable pairings while maintaining consistent margins, radius, and styling.
