This example visualizes the classic Iris dataset, plotting petal length against sepal width as a scatter plot. The visualization uses React components to render SVG elements, with d3.scaleLinear functions handling the x and y axes. The code loads data with d3.csv, applies axes using custom React components, and displays each flower as a circle with a tooltip showing its petal length. The styling uses the Poppins font and a teal color scheme.
