This interactive scatter plot visualizes the Iris dataset, encoding petal and sepal measurements as x/y coordinates while color-coding points by species (setosa, versicolor, and virginica). Built with D3 v6, it uses `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG axes and circles. A `setInterval` cycles through four measurement columns, animating the x-axis mapping across petal width, sepal width, petal length, and sepal length. The visualization includes a fixed y-axis for sepal length, a color legend, and axis labels, with data loaded from a remote CSV via `d3.csv`.
