This example presents an animated scatter plot of the Iris dataset using a reusable D3 chart factory. The plot cycles through different feature combinations every five seconds, animating points between positions with `d3.transition` and staggered delays. The visualization leverages `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom` for scales and axes, while the reusable module pattern allows dynamic reconfiguration of accessors and labels. SVG rendering displays circles that grow on entry and reposition smoothly as the selected x-axis feature changes.
