Dealing with Nodes Coordinates within MindMap TreeModel

Hi,

my question is about coordinates. I’ve read Coordinate Systems but I have not understood everything.

I need to visualize some “text entities” based on a parent child relationship, all around a single central node, so MindMap perfectly fit this need.

I have not understood how to deal with coordinates of each single node. Every node has a property “loc”, but how to define the correct values for X and Y to make sure that the mindmap looks good ?

These examples comme from the sample page :

{"key":0, "text":"Mind Map", "loc":"0 0"},

{“key”:1, “parent”:0, “text”:“Getting more time”, “brush”:“skyblue”, “dir”:“right”, “loc”:“77 -22”},…]

I have no problems with seeting a “key id” for each nodes and a “parent id” for every child node, this data coming from the backend in JSON or whatever.

Is there a way to let GoJS manage the location by itself ?

I ve tried to see what happen if I dont use “loc” and “dir” properties inside nodeDataArray. As expected the result was not really great :)
