I agree with David Woolley that you should recreate it. There are diagramming programs that can convert a flow cart or hierarchical diagram to an outline, but to be honest I don't know where the diagram begins. If you have explanatory text around the diagram you can refer users to that IN SOME CASES. You would have fill in any gaps your explanation leaves out. If you are relying just on the image to be explanatory, then you might have to point visually impaired to a long text description which explains all the links (e.g. Character branches off to Type, ExpPoints, Level.... and you have to explain what the oval means). Here are some real world examples and the solutions we used,although multiple strategies are possible. http://blogs.tlt.psu.edu/projects/accessibilitydemo/examples/imagealttag.html http://blogs.tlt.psu.edu/projects/accessibilitydemo/examples/proofstacks.html Elizabeth P.S. FWIW I think that a more usable diagram visually is easier to accessify for the visually impaired.
