Title: Accessible Images, Diagrams, and Charts Module
Course: Web Accessibility MOOC for Educators > Section: Creating Accessible Images, Diagrams, and Charts

Images, diagrams, charts and graphs use visuals to convey information to readers. If the information provided in the graphic is crucial to the content of the document or web page, it is important not only to provide an alternative text, a caption and/or a text description of the image, diagram, charts and graphs. If charts are complex, providing accessiblity in the form of a table to replicate the chart data is needed. Look at the image to the right. You will notice it has an alt text but the image is not crucial to the information contained in the page. Technically, the image is accessible, however the image has no relevance to the information on this page and should be deleted.
