This visualization presents a dynamic scatter plot of the Iris dataset, split into two subsets that alternate every five seconds. Each plot maps Age against Fare, with points colored by the Sex attribute using D3’s categorical color scheme. The reusable chart module, based on the Towards Reusable Charts pattern, handles SVG rendering, axes, and labels, while a setInterval toggle switches between the two data halves, creating a time-based comparison of the same variables.
