Is canto a cosmos chain?

Excuse me, could you please clarify if "canto" is indeed a part of the "cosmos chain" system? I'm a bit confused as I've heard of Cosmos chain as a blockchain network, but I'm not sure if "canto" is a specific term or component within it. Could you elaborate on the relationship between the two, if any, or if perhaps there's a misunderstanding in my understanding of these terms? Your insight would be greatly appreciated.
