This scatter plot visualizes the classic Iris dataset, showing the relationship between sepal length and petal length across three species of iris flowers. Each species is color-coded—blue for setosa, red for versicolor, and black for virginica—using SVG circles rendered with D3’s `scaleLinear` and `extent` functions. The visualization is built with React and D3 v6, using a decoupled architecture where `VizWrapper` manages the SVG container and the `viz` function handles the rendering, including axes generated with `axisLeft` and `axisBottom`.
