Homonym: Overlay (Layer)
An "overlay" refers to a layer of information or graphics that is placed on top of another image or background. This technique is commonly used in various fields, such as graphic design, video production, and mapping. Overlays can enhance visual communication by adding context, highlighting specific areas, or providing additional data without altering the original content.
In digital applications, overlays can include text, icons, or images that appear temporarily or permanently. For example, in video games, overlays might display player statistics or health bars. In mapping software, overlays can show routes, points of interest, or demographic data, helping users better understand the underlying map.
