A scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal width on the y-axis for individual flowers. The visualization uses React with D3 v5, employing `scaleLinear` for both axes and rendering SVG circles via the `Marks` component. Axes are built with reusable `AxisBottom` and `AxisLeft` components, while a native SVG `<title>` element provides hover tooltips. The data loads asynchronously from a remote CSV using the `csv` function from D3, with numeric fields parsed on ingestion.
