This example shows a scatter plot of the Iris Dataset, mapping petal length against sepal width with points rendered as fixed-size circles. The visualization relies on React for component structure and SVG for rendering, while D3 v5’s `scaleLinear` and `extent` handle axis scaling and domain calculation. Axes are built from reusable React components, and each circle includes a native SVG `<title>` element for tooltips. Data loads asynchronously via D3’s `csv` parser, with numeric coercion applied to all measurement columns.
