This interactive scatter plot visualizes the Iris dataset, encoding petal and sepal measurements as the x and y coordinates of colored circles that represent flower species. Built with D3 v6, it uses `d3.csv` for data loading, `d3.scaleLinear` and `d3.extent` for scales, and `axisBottom`/`axisLeft` for axes. The visualization cycles through different measurement pairings via `setInterval`, updates the x-axis label dynamically, and includes a color-coded legend for the three species.
