In the Python API PivotMDS and MaxEnt both take a dim parameter

but, a pair is assumed in the constructor vector[pair[double, double]]

And, then here in getCoordinates a pair is assumed:

And, anyway, I noticed that writeGraphToGML works in 3D, but if I instead wanted to include the point coordinates in the node data then save as GraphML, how would I do that?

Thanks.
