Save coordinates of all nodes, edges and combos to reload layout in same spot

[bsansone]

Hi, we are trying to implement a feature where a user can drag nodes, combos around and "save" the changes of where they have moved everything. Is it feasible to use graph.save() method to get all the x, y coordinates of all the items and store them for future use? If I import the same data with those coordinates saved, will the graph render exactly the same as when the user "saved" it? Thank you.

Yes this is feasible to do. You would need to save the following fields:

Combo: x, y, collapsed, depth
Edge: curveOffset, curvePosition, endPoint (x,y), startPoint (x,y), type (quadratic, etc.)
Node: layoutOrder, x, y 

along with any of the other basic fields for each item type
