This interactive scatter plot visualizes the Iris flower dataset, allowing users to explore relationships between four measured attributes (sepal length, sepal width, petal length, petal width) by selecting which attribute appears on each axis via two dropdown menus. The visualization uses React to manage component state and render SVG elements, while D3’s `scaleLinear` and `extent` functions handle data scaling and domain calculation. Axis components generate ticks and labels, and circle marks include hover tooltips. The dataset is loaded asynchronously via D3’s `csv` fetch method.
