This scatter plot visualizes the Iris dataset, displaying petal width against sepal length with different species represented by distinct symbol types. The visualization cycles through all four numeric columns every two seconds, automatically updating the x-axis to show a different variable. Built as a reusable D3 module, the chart uses the `scatterPlot` factory function with `scaleLinear`, `axisBottom`, and `axisLeft` from D3 v6. The SVG rendering animates through different column combinations, with axis labels and a title overlaid on the plot.
