This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between different measurements of iris flowers. The visualization uses React with D3.js (v5) for data processing and SVG rendering, incorporating ReactDropdown menus for selecting which variables to plot on the x and y axes. The code demonstrates how to build interactive charts by combining React's state management with D3's scaleLinear and extent functions for axis scaling, while custom Axis components generate the tick marks and labels.
