Review the existing vignettes in the `vignettes/` directory of the skimr repository to understand the expected style and format. Look for any templates or previous examples. The issue requests both simple and advanced use cases, so identify common functions like `skim()` and `skim with()` and demonstrate their usage with sample datasets. Write a vignette in R Markdown that includes code chunks and output. Ensure the vignette compiles without errors.
