This animated scatter plot cycles through different pairings of the four Iris measurements (petal and sepal width/length), using the classic Iris dataset loaded from a gist via d3.csv. Each frame updates the x-axis mapping while points are colored by species (setosa, versicolor, virginica) and include both circular and elliptical markers based on sepal dimensions. The visualization, rendered with SVG and D3’s scaleLinear, axisLeft, and axisBottom, shifts axes and labels dynamically via setInterval, with a fixed legend and title.
