This example presents an animated scatter plot of the Iris dataset, cycling through different sepal and petal measurements on the x-axis while keeping petal width on the y-axis. It uses D3 version 6 to build the visualization, with the `scatterPlot` function creating scales and axes via `scaleLinear`, `axisLeft`, and `axisBottom`. The plot loads data from a CSV file, colors points by species, and includes a legend and titles. A `setInterval` updates the chart every few seconds, and SVG elements render the circles and text.
