Thanks for your comments, Timothy, Alfredo, Kingsley.

An export function is a good idea. However, note that you can use the 
printing functionality of your web browser to generate a PDF (or similar 
output) of the visualization (if you have a corresponding printing 
driver installed on your machine). This PDF can then easily be 
transformed into other formats (SVG, EPS, PNG, etc.). Of course, an 
export function like in WebVOWL would be more comfortable.

An interactive VOWL visualization cannot be extracted from the QueryVOWL 
prototype at the moment. But the SPARQL code of the created QueryVOWL 
graph can easily be copied to the clipboard with the button at the top 
of the results table. This is hopefully helpful to people who do not 
speak SPARQL (fluently).

@Kingsley: I added the DBpedia Live endpoint to the web demo. Thanks for 
the suggestion.
