A scatter plot displays the Iris dataset, plotting sepal length against sepal width for individual flowers. Each point is rendered as a circle using React and SVG, with axes generated from d3-scale linear scales. The code uses d3.csv for data loading, d3.extent and d3.max for domain calculations, and custom React components for axis ticks and marks. Hovering reveals a tooltip with the sepal length value via an SVG title element. The visualization uses a clean grid layout with labeled axes and a teal color for data points.
