[Blindmath] Accessible visual objects by a screen reader

Another thing I forgot to mention, should SVGDraw be more suited to the 
way you want to work, then one possible solution is to use software to 
convert the SVG into a format word can insert. I imagine there are image 
conversion tools out there capable of this, but another option (probably 
not ideal) would be to load the SVG in something like firefox or recent 
versions of Internet Explorer, and then use print and one of the print 
to PDF tools. You probably would need to crop such a resulting PDF, but 
I know that all tools would be free.
