Drawing is an artistic expression that involves marking lines on paper or other materials to visually represent the world. It allows people to express their feelings and create art. There are different types of drawings including sketches, plans, designs, and graphic presentations created using pens, pencils or crayons depending on the purpose. Some common types are life drawings made from direct observation, illustrations that show basic features of objects, cartoons featured in newspapers and magazines, and caricatures that exaggerate structural features of real people.
