This example demonstrates a reusable scatterplot component built with React and D3.js, visualizing the classic Iris dataset. It uses `d3.csv` to fetch and parse the data, `scaleLinear` to map petal length and sepal length to pixel coordinates, and `axisLeft` and `axisBottom` to render the axes. The plot is rendered as SVG via a custom `scatterPlot` function that supports configurable width, height, margins, and radius, following a pattern for reusable D3 charts.
