This animated scatter plot displays the Iris flower dataset, cycling through four different feature pairings on the x-axis every few seconds to highlight relationships between sepal and petal measurements. Circles represent individual flowers, colored by species (Setosa in orange, Versicolor in blue, Virginica in black), with a fixed legend. Built with D3 v6, it reuses a custom `scatterPlot` module that applies `scaleLinear`, `axisLeft`, and `axisBottom` to render axes, while `setInterval` triggers updates and re-renders the SVG elements.
