This animated scatter plot visualizes the Iris dataset, cycling through four different flower measurements on the x-axis while the y-axis remains sepal length. Data points are colored by species (setosa, versicolor, virginica) with a legend and axis labels. The visualization uses D3.js with a reusable `scatterPlot` module that leverages `scaleLinear`, `axisBottom`, and `axisLeft` for scaling and axes. SVG circles represent individual flowers, and a `setInterval` drives the animation, rotating through measurement columns.
