This animated scatter plot visualizes the Iris flower dataset, cycling through four feature combinations on the x-axis while mapping species to color. It uses D3 v6 with a reusable scatter plot module, SVG rendering, and a `setInterval` to update the visualization every few seconds. The code leverages `d3.csv` for data loading, `scaleLinear` and `extent` for scales, and `axisLeft`/`axisBottom` for axes, plus manual legend and label elements.
