This example visualizes the classic Iris dataset, plotting petal length against sepal width as colored circles, with each species distinguished by a distinct color from a `scaleOrdinal` range. The visualization is built with React and rendered as SVG, using D3’s `csv` loader and `scaleLinear` functions to process and scale the data. Axis components (`AxisBottom`, `AxisLeft`) render tick marks and labels, while the `Marks` component generates circles with native SVG `<title>` tooltips. The chart employs a clean, modern aesthetic with Poppins typography and muted axis colors.
