Subset Rows for Clearer Data Comparison

Facets are a way to split your data into subsets and create multiple plots based on those subsets, all within a single visualization. They allow you to display different views of the data side by side, making it easier to compare patterns across groups. For example, if you have a dataset with sales data categorized by region, you can use facets to create separate plots for each region.
