An animated scatter plot of the Iris dataset cycles through four floral measurements on the x-axis while keeping petal width on the y-axis. It uses D3 v6 with reusable modules, including `scaleLinear`, `axisLeft`, and `axisBottom` from the `scatterPlot` function, and renders as an SVG with colored circles representing species. The plot updates every few seconds via `setInterval`, and a legend labeled "Species" identifies the three iris types. Data is loaded as CSV from a remote gist.
