One advantage of graphics presentations is the convenience with which the audience can follow along, while one disadvantage is that data may show a false picture of the situation. Graphics presentations are a popular method to present large quantities of data because almost everyone can understand them. Some people may be unfamiliar with the technical terms used to explain data, but when presented graphically, a clear pattern can be shown.
When presenting vital information, graphics presentations act as a great visual guide to the information being delivered. Many people find it easier to read a chart rather than listening to a set of numbers and trying to make sense of it. Using visual information along with the spoken word is a great way to reach some of the audience who would otherwise be unexcited about what they are hearing.
However, one disadvantage of graphics presentations is that they can be time consuming to construct and may take away from the main point being discussed. Presentations are most effective when free of distractions, and some in the audience may lose focus by diverting attention to flashy graphics in the presentation. Additionally, if graphics presentations are done in a particular way, they can make the numbers look better or worse than they actually are, and some in the audience may be misled by graphics that do not tell the full story.
