This animated scatter plot visualizes the classic Iris dataset, cycling through four flower measurements every two seconds. D3 version 6.7 scales the data linearly along both axes and renders circles with SVG. The reusable scatter plot module employs D3’s selection join for idempotent updates, using `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to redraw axes and marks dynamically, demonstrating responsive full-screen visualization.
