Alternative Text
Adding Alternative Text is useful for persons with disabilities who use screen readers. Once the map is loaded, the screen reader will go through the map content, and the first thing that will be read is the combination of the map title and the alternative text (if the alternative text is specified). Therefore, if there is any kind of special description that should be shared with visually impaired users – it can be specified within the alternative text.
