This interactive scatter plot visualizes the Iris dataset, encoding petal length and width as x and y coordinates while using green, yellow, and red circles to distinguish the three species. The SVG rendering uses D3’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs, with circles positioned via `cx` and `cy` attributes. The example also includes rotated axis labels styled with CSS, loading data from a GitHub Gist URL.
