This animated scatter plot cycles through the four numerical measurements of the classic Iris dataset, switching which measurement is plotted on the x-axis every few seconds while the y-axis remains fixed on sepal length. The visualization uses the D3.js library’s `csv` loader, `scaleLinear` for axes, and a custom `scatterPlot` module. Circles are color-coded by iris species (setosa, versicolor, virginica), with a legend and dynamic axis labels updating as the animation progresses. The plot also displays the raw dataset values mapped to circle `rx` and `ry` dimensions.
