This interactive scatterplot visualizes the Iris dataset, with each point colored by species (setosa, versicolor, virginica) using SVG circles. The animation cycles through different flower measurements, changing the x-axis attribute every few seconds while keeping petal width on the y-axis. The code uses D3 v5's `select`, `csv`, and `scatterPlot` imports, along with `setInterval` to drive the transitions. A legend and dynamic axis labels update as the displayed variables change, all rendered through SVG elements.
