This scatter plot visualizes the Iris Dataset, showing sepal length on the x-axis and sepal width on the y-axis. The code uses React with D3 v5 utilities such as `scaleLinear`, `extent`, and `csv` to load and scale the data, rendering SVG circles with tooltips. Axes are constructed manually via D3’s `ticks()` method, with labels and grid lines styled through CSS classes. The visualization uses a teal color scheme and appears in the Observable-style v3 curriculum, demonstrating a straightforward approach to coordinate mapping and axis generation.
