Here are some examples:
* "Ten thousand saw I at a glance": While technically an exaggeration, this line serves to emphasize the vastness and abundance of the daffodils, creating an image of a truly overwhelming and beautiful sight.
* "Continuous as the stars that shine / And twinkle on the milky way": This simile compares the daffodils to stars, suggesting their beauty and number are comparable to the vastness of the cosmos. This is clearly an exaggeration for emphasis, but it's used to evoke the feeling of being dwarfed by the sheer beauty of the scene.
* "I wandered lonely as a cloud": This is a simile where the speaker compares himself to a lonely cloud, implying a state of solitude before encountering the daffodils. This contributes to the contrast between the speaker's initial isolation and the subsequent overwhelming joy, which might be considered hyperbole in the context of the poem.
Ultimately, "Daffodils" doesn't rely on a single line of hyperbole. Instead, it employs a combination of poetic devices to create a powerful and evocative image of the speaker's experience with the daffodils, leaving the reader to interpret the extent of the exaggeration and the level of hyperbole.
