An animated scatter plot visualizes the Iris dataset, cycling through four feature pairs on the axes to compare petal and sepal dimensions across three species. The D3.js v5 code uses `csv` to load data and `scaleLinear`, `axisLeft`, and `axisBottom` to construct axes. A `setInterval` timer updates the x-value mapping each second, while SVG circles are redrawn with species-specific colors. A legend and axis labels are added dynamically, with text elements recreated on each cycle. The visualization renders in an SVG canvas sized to the window.
