This interactive D3.js visualization displays the classic Iris dataset as an animated scatter plot. It cycles through different pairings of sepal and petal measurements on the x-axis, while the y-axis remains fixed on sepal length. The plot uses SVG circles colored by species (setosa, versicolor, virginica) and updates every few seconds to reveal different data projections. It leverages D3's scaleLinear, extent, axisLeft, and axisBottom APIs, alongside a custom scatterPlot builder that redraws the axes and points with each iteration.
