This example demonstrates a reusable scatter plot that visualizes the Iris dataset, cycling through four numerical attributes (petal width, sepal width, petal length, and sepal length) on the x-axis every two seconds while keeping sepal length on the y-axis. It uses D3.js v6 with `scaleLinear`, `axisLeft`, and `axisBottom` to render axes, and updates the visualization by re-calling the chart function. The plot renders as SVG circles with animated transitions, and the code dynamically binds new data values to update the x-scale domain and circle positions, showcasing a modular chart pattern for interactive data exploration.
