Description of Visual Elements 

Visual elements presented in the form of graphics, charts, or video may not be accessible to blind users, low-vision users, or users with cognitive impairment.   Description of key visual elements (i.e., elements that are only presented visually) in the form of alternative text, long description, transcripts, or audio description, makes these elements more accessible to users.  When describing for educational purposes, the key visual elements are typically those that convey an essential learning goal.
