Data Visualization

The graphical representation of data and information using visual elements such as charts, graphs, maps, and diagrams. While data visualization is a powerful tool for communicating patterns and insights, it presents significant accessibility barriers for people with visual impairments, as most visualizations rely solely on sight to convey meaning. Accessible data visualization requires providing alternative representations such as data tables, textual descriptions, sonification, or tactile graphics so that all users can access the underlying information.
