Is Saga a graphic novel?

Excuse me, I was reading about Saga and I'm a bit confused. I understand it's a popular story, but I'm not sure if it's classified as a graphic novel or something else. Could you please clarify for me? I'm interested in the format of the storytelling and how it's presented. Is Saga indeed a graphic novel, with illustrations and comics-style panels, or does it take a different form? Thank you for your help in clearing this up.
