This scatter plot visualizes the Iris dataset, mapping petal length and width for individual flowers while coloring each point by species (setosa, versicolor, or virginica). The axes are labeled with sepal length and petal length, though the data encoding uses petal dimensions for positioning and sepal dimensions as circle radii. Built with React and d3.v6, the example loads CSV data via `d3.csv`, applies `scaleLinear` and `extent` for scales, and renders SVG circles with attributes driven by the parsed numeric fields. Axis generation uses `axisLeft` and `axisBottom`.
