Graffiti is a form of visual art that involves creating images or text on public surfaces, often using spray paint. It is commonly associated with urban environments and can be seen on walls, bridges, and buildings. While some view it as vandalism, others appreciate it as a legitimate art form that expresses social and political messages. The origins of graffiti can be traced back to ancient civilizations, but it gained prominence in the late 20th century with the rise of hip-hop culture. Artists like Banksy and Jean-Michel Basquiat have brought graffiti into the mainstream, showcasing its potential for creativity and commentary.
