This scatter plot visualizes the Iris dataset, showing petal length against sepal width with each of the three species colored distinctly. The visualization uses React components to render SVG marks, with d3.scaleLinear for the x and y axes and d3.scaleOrdinal for the categorical color mapping. A color legend identifies species, and axes are generated from d3’s tick formatting. The data is loaded asynchronously using d3.csv, while the tooltip displays the petal length value on hover.
