This interactive visualization displays the Iris dataset through a dynamic scatter plot, cycling through different feature pairs on the x-axis every few seconds. The code uses D3’s `scaleLinear`, `axisBottom`, and `axisLeft` to construct the plot, while circles are colored by species (setosa, versicolor, virginica) via a custom marker function. The animation leverages `setInterval` to update the x-axis mapping, with axes, labels, and a legend re-rendered through `selection.call`. Data loads from a CSV URL using D3’s `csv` parser, and the SVG graphic updates in place.
