This scatter plot visualizes the Iris dataset, showing petal width against petal length for individual flowers. Each circle is colored by species using a D3 ordinal color scale, with a tooltip revealing the petal length on hover. The visualization is built with React and rendered as an SVG, using D3’s scaleLinear for axes and scaleOrdinal for categorical colors. Axis components and data marks are structured as modular React components, and the dataset is loaded via D3’s csv parser.
