Feature Request: Export current graph as an image

[stpr-dev]

I found this addon recently, and I quite liked it (I agree with the Wiki that this should be promoted much more, I learned so much from this from just couple of days of observing my browsing habits).

To the main point: It would be nice to have an option to export the graph as an image (preferably svg and/or png image) which can be used for various purposes (such as presentations/sharing with friends etc.)
