graphics-symbol (for icons/signs), graphics-document (complex standalone graphics), and graphics-object (sub-parts). They help screen readers interpret visual information correctly.role="img" with an aria-label or graphics-document makes the graphic perceivable and operable for all users.role="img" is a general image role. graphics-symbol is more specific for icons and simple graphics that convey a single idea (like a gear icon). It tells assistive tech that the graphic is symbolic, often used with aria-label for a short text alternative.<svg role="graphics-symbol" aria-label="Settings">...</svg>. The role defines the type of graphic, and the aria-label provides the accessible name.<svg>, missing accessible names when roles are present, and <g> elements without role="group" when they contain relevant structure. It also suggests roles based on element type (e.g., <path> with aria-label â graphics-symbol).role="img" or graphics-symbol where appropriate, and inserts an aria-label placeholder if missing. You should replace the placeholder with meaningful text.Highlight elements with ariaâdescribedby and see the linked description text. Verify a11y annotations.
