Business graphics, charts and diagrams used in a presentation. Presentation graphics software provides predefined backgrounds and sample page layouts to assist in the creation of computer-driven slide shows, which, in combination with a data projector, made the 35mm slide presentation obsolete. Navigation from page to page (slide to slide) can be done manually or automatically every so many seconds. The most popular presentation software is Microsoft PowerPoint (see PowerPoint). Frames and Transitions The format is a series of horizontal frames (slides) with transitions between them. Images, text, audio and video are laid out on the frames, and speaker's notes can be added. Like any page layout program, elements on a frame can be moved around and resized.
