[Feature request] Download graphs

Dear all,

sometimes graphs, when they are big or complex, are hard to see and explore.

As a documentation reader, sometimes I need a bigger window to see Ford graphs.

How to do that?

I really don't know, but 2 alternatives come to my mind:

1. Add a button to see the graphs in the whole screen
2. Add a button to download the image (SVG) and I will open the picture locally with my preferred tool/viewer.

Option 1 is nice to have "everything on the browser", but option 2 seem to be more versatile. In addition, with option 2 you can directly take this graphs and use them in a document/article, edit the picture, etc ...

I found issue #97 and (in the past) it seems that the second option could be easier to implement.

What do you think? Is it an interesting feature for other devs?

Thanks in advance,
BR.
