This interactive scatterplot visualizes the Iris dataset, showing petal width against sepal length with points colored by species. Using D3.js and SVG, the plot animates through different variable combinations every few seconds, cycling through all four flower measurements as axes. The visualization updates axes and scales dynamically via `setInterval`, while a legend identifies the three species with distinct colors. Built with `d3.csv`, `d3.scaleLinear`, and axis components, it demonstrates a reusable scatterplot module with real-time data exploration.
