This scatter plot visualizes the Iris dataset, mapping petal length and width as point positions, with sepal length and width stored as additional data properties. Points are colored by species (red, green, pink) using a switch statement. The visualization uses D3 v6’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to load data, scale coordinates, and render SVG axes. The code sets fixed radius circles, handles viewport-sized dimensions, and displays axis labels with custom styling.
