This animated scatter plot displays the Iris flower dataset, cycling through four feature combinations on the x-axis while y remains sepal length. Colored circles represent species (skyblue, lightgreen, orange), with a legend and titles. Built with D3.js (v6), it uses `scaleLinear`, `axisLeft`, `axisBottom`, and a custom `scatterPlot` module, re-rendering SVG elements via `join` on a timer.
