This scatter plot visualizes the Iris dataset, encoding petal length and petal width as x and y coordinates, while coloring each point by species. The code also reads sepal length and width values into the `rx` and `ry` attributes of each circle, though these do not affect the visual rendering since `r` is set to a fixed radius. Built with React and D3 v6, it uses `d3.csv` for data loading, `d3.scaleLinear` for scales, and `d3.axisLeft`/`d3.axisBottom` for axes with custom labels.
