Abstract
This article proposes a natural language-based approach to accessibility of charts. Formal underpinnings are used to semantically annotate the constituent elements of a vector graphic to support accessing and modifying the content by natural language queries in a web interface. A prototype which lets blind users perform a number of analytical activities on bar charts is introduced.
