This animated scatter plot explores the classic Iris dataset, cycling through four feature pairings every two seconds. The visualization colors each species differently—setosa in green, versicolor in indigo, and virginica in red—using D3’s `selectAll` and `.join` to update SVG circles smoothly. The chart is rendered via a custom `scatterPlot` module that leverages D3’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` for axes and scaling, while the interval-based animation shifts the x-axis mapping between petal and sepal measurements.
