Daisy Buchanan is a central character in F. Scott Fitzgerald's novel 'The Great Gatsby,' representing the elusive American Dream and the complexities of love and wealth in the Jazz Age. She is depicted as beautiful and charming but also shallow and self-centered, embodying the contradictions of the 1920s elite and the social mores of her time. Daisy's relationships, particularly with Jay Gatsby and her husband Tom Buchanan, reveal the destructive nature of desire and the unattainable ideal of happiness.
