Section 508 of the Rehabilitation Act requires that Federal agencies' electronic and information technology be accessible to people with disabilities. Text and tables on the Web are generally accessible to the visually impaired individual using a screen reader. A graphic image such as a picture can be made accessible with descriptive text called an Alt tag. Graphs and maps are more challenging. The Cancer Mortality Maps & Graphs Web site (http://cancer.gov/atlasplus/) addresses the graph challenge using dynamically-generated text files, which describe all components of the graph.
