This visualization demonstrates a reusable scatter plot displaying the Iris dataset, cycling through four attribute combinations every two seconds to compare petal and sepal measurements. Built with D3.js v6, the chart uses `scaleLinear` and `extent` for scales, `axisLeft` and `axisBottom` for axes, and SVG circles for data points. The code implements a reusable chart pattern with configurable accessors, and the animation transitions between different x-axis variables using `setInterval` while maintaining a fixed y-axis of sepal length. The implementation includes a custom font and full-window responsive sizing.
