What are murals and graffiti, and how do they contribute to urban art culture?

Murals are large paintings or artworks typically found on walls or buildings, often created with permission and intended to beautify a space. Graffiti, on the other hand, refers to unauthorized markings or drawings on public surfaces. Both murals and graffiti contribute to urban art culture by adding color, creativity, and expression to city landscapes, sparking conversations, and reflecting the diverse voices and perspectives of the community.
