Document composition is a way of organizing and arranging information so that it is easy to understand. It uses things like headings, paragraphs, and graphics to make the information clear and easy to read. For example, if you wanted to make a document about a trip you took, you might use headings like "Places I Visited" and "Things I Learned" to help make it easier to understand. You could then use paragraphs to write about each place you visited and what you learned there. You could also use graphics like pictures or maps to make the document more interesting.
