This example demonstrates an animated scatter plot that cycles through different Iris dataset columns, updating the x-axis values every two seconds. The visualization uses D3.js version 7.8.0 with a reusable `scatterPlot` function that employs SVG rendering. It uses `scaleLinear`, `scaleOrdinal`, `symbols`, and `transition` to animate the movement of data points, while `axisLeft` and `axisBottom` generate the labeled axes. The plot displays different Iris varieties with distinct symbols, and hovering over a point changes its color from black to red.
