Drawing live from the Iris dataset, this animated scatter plot cycles the x-axis between petal width, sepal width, petal length, and sepal length. Colored circles distinguish the three species using custom markers. The visualization is built with D3 v6’s `scaleLinear`, `axisLeft`, `axisBottom`, and `csv` loader, with a `setInterval` updating the plot’s x-value and re-rendering SVG elements.
