This interactive scatter plot animates through the four numerical measurements of the Iris dataset, cycling the x-axis every two seconds while keeping sepal length on the y-axis. D3’s `scaleLinear`, `scaleOrdinal`, and `symbol` APIs render distinct species shapes with axis ticks. The visualization uses `setInterval` and the `scatterPlot` reusable function, processing data loaded via `d3.csv` from a GitHub Gist, with an SVG output.
