This scatter plot shows the relationship between sepal length and sepal width for Iris flowers, with each circle representing a sample and a tooltip revealing its exact measurement. The visualization uses React components to render SVG axes and marks, with D3 v7 scales (`scaleLinear`), `extent`, and `format` handling data mapping and tick labels. Data loads asynchronously via `d3.csv` from a remote Iris dataset, and the chart includes rotated axis labels for clarity.
