This scatter plot visualizes the Iris dataset, mapping petal length and width for each flower specimen while coloring points by species (setosa, versicolor, or virginica). Built with D3 v6 and React, it uses `d3.csv` to load data, `d3.scaleLinear` for axes, and `d3.axisLeft`/`d3.axisBottom` for ticks. The SVG circles use attributes `rx` and `ry` to encode sepal dimensions, though these are not visually discernible because the radius remains fixed. The plot fills the viewport with axis labels in red.
