Illustrations are visual representations that help convey ideas, stories, or concepts. They can be found in books, magazines, and online, enhancing the text by providing a clearer understanding of the content. For example, a children's book often includes colorful illustrations to engage young readers and spark their imagination. Artists create illustrations using various techniques, such as drawing, painting, or digital design. These images can range from simple sketches to detailed artwork, depending on the purpose. Illustrations play a crucial role in fields like advertising, education, and graphic novels, making information more accessible and enjoyable for everyone.
