This animated scatter plot demonstrates how correlations among four Iris flower measurements shift as the axes cycle through different attribute pairs. D3's `scaleLinear` maps values to coordinates, while `axisLeft` and `axisBottom` render the changing scales. The visualization cycles the x-axis through petal width, sepal width, petal length, and sepal length, recolors points by species, and uses SVG circles for marks. It loads the classic Iris dataset from a GitHub-hosted CSV via `d3.csv`.
