This example visualizes the Iris Dataset, mapping petal length on the x-axis and sepal width on the y-axis in a stylized scatter plot. A React component loads the CSV data with `d3.csv` and uses `d3.scaleLinear` to compute scales. Axes and circle marks are rendered as SVG elements with separate components, while CSS styles the ticks, labels, and marks with the Poppins font. Native SVG `title` elements provide hover tooltips.
