The export should be saved by name

This give a new browser window

# javascript
window.open("data:text/plain;Content-Disposition:attachment;filename=graphapi.txt,howdy");

This js and issue should be moved to github but for now moved to graph_phyz component.

The export done by firefox is saved as a .part file.

The colors are not saved into the file.

We could wonder why not just use the Graphviz project?

Maybe this helps http://stackoverflow.com/questions/7717851/save-file-javascript-with-fil...

Is should be possible now with https://drupal.org/project/blob_relay.

It needs integration code so let's see how that works out.

The link from #5 to http://stackoverflow.com/questions/14964035/how-to-export-javascript-arr... has a new comment
document.body.appendChild(link);
which would make it work on FF ... need to try.
