This example demonstrates how to create high-quality scatterplots using base R graphics, covering both basic and intermediate plotting techniques. It uses the built-in `trees` and `iris` datasets to show relationships between variables, including girth versus volume for black cherry trees and sepal length versus petal length for iris species. The code illustrates core R functions like `plot()`, `rep()`, `par()`, and `axis()`, with features such as custom point characters, colors, legends, best-fit lines, confidence intervals, and multipanel layouts.
