Charts, Diagrams, and Timelines
Authors of informational texts often use graphics to convey information. Graphics are visual tools such as charts, graphs, diagrams, and timelines. These visuals help you to better understand a text; they may even give you extra information that is not in the text.
A chart is a graphic that organizes information. It uses columns and rows. Each column has a heading in bold print at the top. The headings tell you what the information in each column is about.
A diagram is a simple drawing with labels to make something easier to understand. A diagram may show the different parts of an object. A diagram may also show how something works, how to put something together, or how to play a game.
Another kind of graphic took is a timeline. Authors writing about history and science often use a timeline to show the dates when important events happened. Timelines make it easy for you to see the order in which events take place.
