This interactive scatter plot visualizes the Iris flower dataset, mapping petal length against sepal length with points colored by species. The visualization is built using React and D3, employing a reusable chart pattern where a `scatterPlot` function generates the SVG rendering. The code uses D3's `csv` loader to fetch data, `scaleLinear` for axes, and `axisLeft`/`axisBottom` for tick marks. The chart connects D3 data joins with CSS classes for species-based color coding, demonstrating a modular approach to building configurable visualizations in React.
