This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis and sepal length on the y-axis. It uses D3 v6 with SVG rendering, loading the data via `d3.csv`, scaling with `scaleLinear`, and computing domains through `extent`. Axes are generated with `axisLeft` and `axisBottom`, while circles are positioned using `data` joins. Axis labels are appended as SVG text elements, and the chart fills the browser window by setting its width and height to `window.innerWidth` and `window.innerHeight`.
