This example shows the Iris Dataset as an animated scatter plot, cycling through different pairings of flower measurements every two seconds. The plot is built with D3 v6, using `scaleLinear` for axes, `axisLeft` and `axisBottom` for ticks, and a reusable chart function that updates circles and axes in response to changing data accessors. The visualization uses SVG rendering and a custom `setInterval` loop to switch between four measurement columns.
