This scatterplot visualizes the Iris dataset, mapping sepal length on the x-axis and sepal width on the y-axis, with each flower’s species encoded by a circular mark. The React-based chart uses d3.scaleLinear for both axes, d3.extent to compute domains, and custom SVG axis components with tick labels formatted via d3.format. Data loads asynchronously through d3.csv, and each circle includes a native SVG title tooltip showing the sepal length value.
