This scatter plot visualizes the Iris dataset, mapping petal width on the x-axis against petal length on the y-axis using a linear scale. The React-based visualization renders circles as SVG marks, with axes generated by custom React components that leverage d3’s scaleLinear and extent functions. Hovering over each circle reveals its value via a native SVG title tooltip. The chart is styled with Poppins font and muted colors, with axis labels and tick formatting applied through d3’s format function.
