This interactive scatter plot, built with D3 v6, visualizes the Iris dataset. It cycles through four feature combinations (sepal and petal dimensions) on the x-axis, updating every few seconds while the y-axis remains sepal length. Data points are colored by species (Setosa, Versicolor, Virginica), with a static legend and axis labels. The visualization uses SVG for rendering and animation, with axes and scales computed via `scaleLinear`, `extent`, and `axisLeft`/`axisBottom` from the D3 API.
