Graffiti art is a form of visual expression that involves creating images or text on public surfaces, often using spray paint. It can be found on walls, buildings, and other structures, and is sometimes considered a way to communicate social or political messages. While some view it as vandalism, others appreciate it as a legitimate art form that adds color and character to urban environments. Many graffiti artists, such as Banksy and Jean-Michel Basquiat, have gained recognition for their unique styles and thought-provoking works. Graffiti art often incorporates elements of street culture and can include various techniques, such as stenciling and mural painting, making it a diverse and dynamic medium.
