This fork of a reusable D3 scatter plot animates through the four numeric columns of the Iris dataset, cycling every two seconds. It visualizes the flower measurements as circles colored by species, with axes and a legend. The implementation uses D3 v6 APIs including `scaleLinear`, `scaleOrdinal`, `axisLeft`, and `axisBottom` within a custom `scatterPlot` function, and renders to SVG with an animated update via `setInterval`.
