This animated scatter plot visualizes the Iris dataset, cycling through four feature pairs to reveal relationships between sepal and petal measurements. Colored points distinguish the three iris species (setosa, versicolor, and virginica) with a color legend. Built with D3 v6, the visualization uses `d3.csv` to load data, `scaleLinear` with `extent` for axes, and `setInterval` to switch axis variables, re-rendering the chart with `axisBottom` and `axisLeft` while updating labels and titles dynamically.
