Here is a simplified visual that shows how working with one or more of the three characteristics corrects perceptual distortions and ultimately leads to the arising of the possibility of freedom.
Impermanence
Unsatisfactoriness
Impersonality
Seeing that which is impermanent as permanent
Seeing that which is unsatisfactory as fulfilling
Seeing that which has no essence as me or mine
Signlessness
Desirelessness
Emptiness
