Faceted Plots Enhance Data Comparison
Layout plots help you split data into subsets and create multiple plots within a single chart. This technique allows you to display different views of your data side by side, making it simple to compare trends and patterns across groups. For example, if you are analyzing sales data by region, facets can generate separate plots for each region, providing clearer insights. Learn how using facets can improve your data analysis and storytelling.
