Clockwise adds a sharp
Move one step clockwise and the tonic rises by a perfect fifth. In major keys the signature gains one sharp until the enharmonic turn near F♯/G♭.

Counter-clockwise adds a flat
Move left and you travel by perfect fourths. Neighboring keys differ by only one scale tone, which is why they are closely related.
Relative keys share a signature
The inner ring shows each major key’s relative natural minor. The two scales use the same notes but center the harmony on different tonics.
