The circle is basically a map of the key's. If you look at it as if it were a pie and every song has a piece of that pie. For example, if I'm learning a song and I decide that the key tone I'm hearing is F, then I look at F on the circle then quarterise the circle so I only see F & one note either side & the minors in the middle then I can see the basic chords that are used in that piece. Provided that my initial assessment was correct and the song is indeed in F, then I don't need to faf about looking for the right chords because the circle tells me what they are.
I hope that makes sense.
