This interactive scatter plot cycles through combinations of Iris dataset measurements, animating between different petal and sepal dimensions every two seconds. It uses D3’s `scaleLinear` for axes, `axisLeft` and `axisBottom` for ticks, and data joins to update circle positions. The visualization is rendered as SVG, with each circle’s radius fixed at 5 pixels, and supports dynamic axis rescaling based on the current x-value column.
