This scatter plot visualizes the Iris dataset, encoding flower measurements on both axes and using different symbol shapes for each species. It cycles through four measurement columns every two seconds, updating the x-axis position and scale with a smooth transition. The visualization is built with D3 v7, using `scaleLinear`, `scaleOrdinal`, `symbol`, `axisLeft`, and `axisBottom`, and renders as an interactive SVG with animated transitions driven by `setInterval`. Data is loaded asynchronously from a CSV file using D3's `csv` function.
