Nodes are created at position (0, 0, 0) by default which seems to break the layout algorithms in Gephi.

Fix is to specify differing x, y starting positions. It doesn't seem to like floats either. They must be ints? (or I see NaNs for x, y positions in the node viewer).

Up to you of course, but I suspect this can be fixed in the documentation in the README.md file.

(Also while I'm at it the default workspace is workspace="workspace1" now I think not workspace0 as it appears in the README.md file).

Finally.. thanks for taking the time to put this code up here. Saved me a lot of time.
