This example visualizes the Iris Dataset as a scatter plot, mapping petal length on the x-axis against sepal width on the y-axis for the first thirty observations. Built with React and D3 v5, it renders SVG marks and axes using custom components like `AxisBottom`, `AxisLeft`, and `Marks`, which leverage `d3.scaleLinear` and `d3.extent` for scaling and domains. The plot features formatted tick labels via `d3.format` and interactive tooltips through SVG `<title>` elements.
