This scatterplot visualizes the Iris dataset, plotting sepal length against sepal width for individual flower samples. The code loads CSV data via the `d3.csv` utility and renders the points as circles using React components with SVG. Axes are constructed with `d3.scaleLinear` and custom tick components, while D3’s `extent` and `max` functions determine the scales’ domains. The visualization uses a clean, minimal design with teal markers and labeled axes, providing a straightforward view of the distribution and relationship between these two measurements.
