This scatter plot visualizes the Iris dataset, mapping petal length and width to axes while coloring points by species. The SVG rendering uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. Data is loaded from a CSV via `d3.csv`, with circles positioned using `cx` and `cy` attributes and colored through a species-based switch statement. The plot fills the browser window, with tick labels enlarged to 24 pixels.
