A "viewgraph" is a transparency used with an overhead projector to display information to an audience. It's an older method of presentation. 📜 Think of it as a clear sheet with text or images that's projected onto a screen. Viewgraphs were commonly used in classrooms and business meetings before PowerPoint became popular. They allowed presenters to easily share visual aids with a group. They are now largely replaced by digital projectors and presentations.
