This interactive scatter plot visualizes the Iris dataset, cycling through four different floral measurements on the x-axis over time while plotting petal width against sepal length. It uses D3 v6 to render animated SVG circles colored by species, with the y-axis fixed and the x-axis rotating automatically via `setInterval`. A legend identifies the three species, and axis labels update dynamically to reflect the current dimension. The code relies on D3’s `csv` import, `scaleLinear` scaling, and custom `scatterPlot` API.
