This animated scatter plot cycles through the four Iris flower measurements, displaying them on the x-axis one at a time. The visualization uses a color-coded marker system to distinguish between the three species of Iris flowers within the dataset. The animation is driven by a `setInterval` function that updates the scatter plot's x-axis data every two seconds. The plot is rendered using SVG and built with the D3.js library, leveraging its modules for data parsing, linear scaling, and axes creation. The Iris dataset is loaded from a remote URL in CSV format.
