An animated scatter plot displays the Iris dataset, cycling through four flower measurements on the x-axis while keeping sepal length on the y-axis. Circles represent individual flowers, colored by species (setosa, versicolor, virginica) with a legend and axis labels. Built with D3 v6, the visualization uses `scaleLinear`, `axisLeft`, and `axisBottom` within a reusable `scatterPlot` module, and updates via `setInterval` to rotate the x-axis variable every few seconds.
