Rdf validator graph drawer

Hello guys,

I don't know if you can take a request like this but if you do, please make
an option in the graph drawer to replace the namespaces with its names
(eg. rdf:type instead of http://www.w3.org/1999/02/22-rdf-syntax-ns#rdf).
The visual representation would be SO much better and usable.

Thanks,
