This interactive scatter plot uses the classic Iris Dataset, rendered as an SVG in React, to explore relationships between four numeric measurements. Menus built with React-Dropdown let users dynamically select which attributes map to the x and y axes, while d3.scaleLinear and d3.extent compute the scales for each new selection. Axis components and data marks are custom React components that use D3 for tick generation, and a `<title>` element provides a tooltip. The chart deliberately sets `height` shorter than the container to reserve space for the dropdown controls.
