This animated scatter plot cycles through different Iris flower measurements on the x-axis, plotting petal width, sepal width, petal length, and sepal length in sequence. The visualization uses D3.js v6 (d3.csv, d3.scaleLinear, d3.axisLeft, d3.axisBottom) to render SVG circles and axes, with hard-coded color coding by species above a legend. The x-axis label and scatter positions update every few seconds via setInterval, while the y-axis remains sepal width. Data comes from a gist-hosted CSV of the classic Iris dataset.
