This fork of a scatter plot visualizes the classic Iris dataset, allowing interactive exploration of relationships between sepal and petal measurements. The React-based graphic uses D3 scale functions (`scaleLinear`, `scaleOrdinal`) to map data attributes to x/y positions and categorical species to a color legend. Two dropdown menus let users select which numerical attributes to compare, while the SVG rendering updates immediately. The color legend encodes the three Iris species using distinct hues. The code demonstrates a modular approach with separate components for axes, marks, and the legend, using D3 utilities for data loading, scaling, and tick formatting.
