This example visualizes the classic Iris dataset, plotting petal length against sepal width for three species of flowers. The scatter plot uses distinct teal and purple color coding to differentiate species, with hover tooltips revealing each point’s species name. Built with React and D3 v5, it uses `scaleLinear`, `csv` for data loading, and custom SVG `AxisBottom` and `AxisLeft` components. The `Marks` component renders circles with a fixed radius of 10 pixels, while axis styling and font are customized through CSS, including the Poppins typeface.
