This animated scatterplot cycles through the four Iris flower measurements, using petal width, sepal width, petal length, and sepal length as the x-axis variable while keeping sepal length on the y-axis. Points are colored by species (setosa, versicolor, virginica) with a static legend, and the chart updates via `setInterval`. Built with D3 6.7.0, it loads CSV data from a GitHub Gist, uses `scaleLinear` and `extent` for scaling, and renders axes with `axisLeft` and `axisBottom`. The SVG visualization is regenerated each cycle, with axis labels and title redrawn dynamically.
