This animated scatterplot cycles through the Iris dataset’s four numeric attributes, using D3’s `scaleLinear`, `scaleOrdinal`, `axisBottom`, and `axisLeft` to map petal and sepal measurements. A `transition` with a one-second delay animates point positions and axis updates every three seconds. The chart colors points by species using a viridis palette and applies `symbols` and `symbol` scales, though only circles render. The x-axis label updates dynamically, while the SVG canvas fills the viewport.
