This scatter plot displays sepal length against sepal width from the Iris dataset, with each flower represented as a circle that can be clicked to highlight its selection. The React app uses a ResizeObserver to track container dimensions and re-renders the SVG visualization when data or selection changes. Built with D3 v7, it leverages scaleLinear, extent, axisBottom, axisLeft, and data joins to render circles and axes, with labels and margins configurable through props.
