This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis and sepal length on the y-axis. The SVG rendering uses D3 v6 APIs including `csv` for data loading, `scaleLinear` for axes, and `axisLeft`/`axisBottom` for tick marks. Circles represent individual flowers, with a fixed radius and no color encoding. The chart fills the browser window, with axis fonts enlarged via CSS for readability.
