This example shows an animated scatter plot of the Iris dataset, cycling through different combinations of sepal and petal measurements on the x-axis while keeping petal width on the y-axis. Data points are colored by species, with a legend and axis labels updating dynamically. Built with React and D3 v6, it uses the `scatterPlot` reusable chart function, `scaleLinear`, `axisLeft`, `axisBottom`, and `setInterval` to update the x-value mapping. The SVG rendering includes animated transitions and custom styling via CSS.
