This scatterplot visualizes the iris dataset, plotting sepal length against sepal width. The visualization uses D3 utilities like `scaleLinear` and `extent` to compute scales, while React components render the SVG elements. The axis labels and tick marks are styled with the Poppins font, and the data points are rendered as circles with tooltips provided by SVG `<title>` elements. The plot demonstrates a clean integration of D3's data-handling with React's component-based rendering.
