This animated scatter plot cycles through four Iris flower measurements on the x-axis, visualizing the classic Iris dataset. Color-coded circles represent the three species, with a legend identifying each. Built with D3 v6, the visualization uses an interval timer to swap the x-axis variable among petal width, sepal width, petal length, and sepal length, redrawing the chart and axis labels with each change. The scatter plot is constructed using D3's scaleLinear, axisBottom, and axisLeft functions to render the SVG.
