What report shows data segmented by channel?

The Channels report in Google Analytics groups traffic sources into high-level categories like Organic Search, Direct, Referral, Social, and Paid Search. This provides a clear overview of how different marketing efforts are performing. Segmentation is a feature that allows you to isolate and analyze subsets of your data, but it's not a report itself. Source/Medium is a report that shows more granular detail about where your traffic came from (e.g., google / organic, facebook.com / referral), but it's not segmented by the broader channel groupings. Attribution refers to models used to assign credit to touchpoints in a conversion path, not a report showing channel-level data.
