What is one way visuals enhance a written piece?

Visuals enhance a written piece primarily by providing additional context and illustrating concepts. This is crucial because they help clarify and reinforce the written content, making complex ideas more accessible and understandable to the reader. For instance, a chart or graph can succinctly display data trends that might require lengthy explanation in text form. Similarly, images can evoke emotions or establish a setting that enriches the narrative, allowing readers to visualize and connect more deeply with the material. By complementing the text, visuals can engage readers and promote retention of information, thereby elevating the overall effectiveness of the written piece.
