This animated scatter plot displays the classic Iris dataset, mapping petal width against sepal length while coloring each point by species: pink for setosa, red for versicolor, and blue for virginica. The visualization uses d3.csv to load data from a GitHub-hosted CSV file and renders SVG circles with dynamic fill colors. Every two seconds, a setInterval callback cycles the x-axis through different measurement columns—petal width, sepal width, petal length, and sepal length—using a reusable scatterPlot module built with d3.scaleLinear, d3.axisLeft, and d3.axisBottom. The axes update smoothly while circle positions remain based on the current x-value mapping.
