Explanation:
This poem uses the visual form of the words to create a picture of rain. The slanted lines and the dots resemble falling raindrops. The overall shape mimics a cloud, with the "rain" falling from it. This poem relies on the visual aspect of the language to convey the meaning, rather than just the words themselves.
This is a simple example, but concrete poetry can be incredibly complex and sophisticated, using a wide range of techniques to create visual effects and convey emotions.
