This example displays the classic Iris dataset in a scatter plot, cycling through the four measured attributes on the x-axis every two seconds to reveal different correlations with sepal length on the y-axis. Each point is rendered as an SVG circle, and the axes rescale dynamically as the data mapping changes. Built as a reusable D3 chart, it employs `select`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` from the D3 library. The animation is driven by a `setInterval` callback that updates the chart’s configuration and re-invokes the plotting function.
