Graphics
Graphics provide illustrated information to readers. In general, graphics are designed to make it easier for readers to understand your data. Deciding when to insert a graphic depends on the information you need to convey. For example, as you're writing a technical report, you find yourself struggling to describe a complex concept. Fitting your description within a few paragraphs is impossible, so you decide to create a graphic. Often, graphics are useful when concepts, designs, or processes are too complex or cumbersome to describe in written or oral form.
