In which way does Shakespeare portray Portia's generous nature?

Portia has a good idea what she is going to do before the trial of Shylock. She gives Shylock the chance to concede his bond on Antonio before disaster befalls him. She offers Shylock compensation for loan but Shylock refuses.

Portia willingly offers bassanio to leaver her just after the moment of wedding to save his best friend Antonio while she even offers 20 times of the original sum-2000 Ducats to save antonio

She treats Lorenzo, Jessica, Gratiano, and nerissa with utter respect even after the fact that she ranks way higher then them.

She also acts nice and friendly towards all her suitors whome she utterly disliked and would've never wanted to marry
