Illustration is a form of visual art that involves creating images, typically in a two-dimensional format, to enhance or complement written content, convey ideas, tell stories, or communicate messages. Illustrations can be found in various mediums, including books, magazines, advertisements, websites, animations, and more.

Illustrators use their artistic skills and creativity to bring ideas and concepts to life through visual representation. They may work with traditional mediums such as pencils, pens, watercolors, or create digital illustrations using graphic design software and tablets. Illustrations can vary in style, from realistic and detailed to abstract or cartoonish, depending on the desired aesthetic and purpose.
