Bitmapped graphs are the most frequently found form of graph contained on web pages. However, users who are blind or visually impaired currently find it difficult or impossible to access the data contained within such graphs, typically relying only on the ALT text description. This paper details an approach to creating bitmapped graphs for visually impaired users to access on the Internet. The process employs a combination of manual intervention from a web developer, and novel automatic algorithms that are specific for graph-based images. The approach identifies the important regions of the graph and tags them with meta-data. The meta-data and bitmap graph are then exported to a web page for sonification and exploration by the visually impaired user.
