This scatter plot visualizes the Iris Dataset, mapping petal length to the x-axis and sepal length to the y-axis. D3 code uses `csv` to load data, `scaleLinear` and `extent` to set scales, and `axisLeft` and `axisBottom` for axes. Each flower is rendered as an SVG circle with a fixed radius. The visualization fills the browser window using `window.innerWidth` and `window.innerHeight`.
