This example visualizes the classic Iris Dataset, plotting petal length against sepal width as a scatter plot. The visualization uses React to render SVG circles and axes, with D3 (v5) for data loading, scaling, and axis generation. A `Poppins` font style is applied to the page, while the marks are styled with a teal fill and the axes use light gray tick lines. The code includes a formatted tick label function that abbreviates values using D3’s `format('.2s')`.
