This scatter plot visualizes the iris dataset, mapping petal length on the x-axis and sepal width on the y-axis. Each point represents a flower specimen, colored by species using an ordinal color scale, with a legend showing the species categories. The visualization is built with React and D3 v5, using `scaleLinear` and `scaleOrdinal` for scales, `extent` for domain calculation, and custom SVG components for axes, marks, and the color legend. Data is loaded asynchronously from a remote CSV using D3’s `csv` method.
