This example visualizes the Iris Dataset as a stylized scatter plot, mapping petal length to the x-axis and sepal width to the y-axis. Built with React and D3 v5, it renders SVG circles with tooltips via nested `<title>` elements. The code uses `d3.csv` for data loading, `scaleLinear` for coordinate mapping, and custom React components (`AxisBottom`, `AxisLeft`, `Marks`) to generate axes and data points with Poppins typography and a teal color scheme.
