Scatter Plot
This scatter plot displays the relationship between petal length and petal width, with points colored by iris species. Built with Observable Plot and D3 v7, the example loads CSV data via `d3.csv` and `autoType`, then renders a full-window plot using Plot’s `plot` and `dot` marks. The chart updates to fill the browser viewport by setting width and height to `window.innerWidth` and `window.innerHeight`.
