It's only loosely based on Don Juan's legend, in terms of womanizing. There are several elements he added are different Freudian stuff:
1) the opera was completed about 1/2 yr after his father's death.
2). at the beginning of the play, a father (Anna's) was killed by the protagonist
3). then the dead father came back as the Commendatore to carry Giovanni to hell
