This scatter plot visualizes the Iris flower dataset, positioning each specimen by its petal width against sepal length with a fixed channel mapping color to species (red for setosa, orange for versicolor, white for virginica). Built with D3 v6, it leverages the `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to construct axes and render SVG circles. The visualization demonstrates a reusable scatter plot module that updates its x-axis mapping cyclically through the dataset’s numeric columns, though the current example only displays one configuration.
