This scatter plot displays the relationship between petal length and sepal width in the Iris dataset. The visualization renders as an SVG, with the data loaded asynchronously via `d3.csv` and parsed using a custom row-mapping function. Axes are constructed with `d3.scaleLinear`, using `.domain()`, `.range()`, and `.nice()` to establish the scale. The React application manages state transitions, displaying a "Loading..." message until the dataset arrives, then drawing each point as a circle element with its horizontal and vertical positions mapped through the corresponding scales.
