This animated scatter plot visualizes the Iris dataset, allowing selection of X and Y axis variables from menus. It uses D3 v6 with SVG rendering, implementing a reusable chart pattern with selection.join for enter, update, and exit transitions. Axis labels animate position changes, circles transition to new coordinates with staggered delays, and a tooltip appears on mouseenter. The scatterPlot module uses scaleLinear and scalePoint for quantitative and categorical axes, with d3.transition for smooth 1000ms animations.
