This scatter plot visualizes the relationship between sepal length and sepal width from the Iris dataset, fetched as a CSV via D3’s `csv` loader. It renders 150 circles using React components for axes and marks, with a linear `scaleLinear` mapping both dimensions. The SVG includes styled tick lines, labels, and a Poppins font, while hover tooltips show formatted values via the `<title>` element. The chart applies `.nice()` to round the x-axis domain and uses D3’s `extent` and `format` utilities for tick formatting.
