Graphical Semantic Enhancement

The practice of enriching graphical objects with meaningful text labels, descriptions, and metadata so that they can be understood non-visually. In accessible drawing and diagramming tools, graphical semantic enhancement allows users to assign descriptive labels to shapes, regions, and objects, transforming purely visual content into information that can be explored through speech or other assistive technologies. This concept extends to modern web practices such as adding alt text to images, labeling SVG elements, and providing accessible descriptions for data visualizations and interactive graphics.
