Use predefined coordinates for nodes about force-graph

[vasturiano]

@havardl thanks for reaching out. You can attribute coordinates to nodes by setting x and y attributes in each of the node objects. The framework will respect that as their starting positions.
Then I would recommend setting cooldownTicks(0) which will tell the force engine to to not run any iterations. This should make your nodes layout fixed.

Hello! I also have a large graph (47k nodes and links). May I know @havardl what results/improvements did you get with the suggestions made by @vasturiano ?

Hey @soccerdroid, I actually ended up going back to my original implementation with Sigma.js for this specific task after figuring out how to turn of edges rendering which decreased the rendering time of the graph.

But I assume importing the nodes with x and y coordinates in the json file and then updating the node objects would work just as well here.

Thank you @havardl . If possible, could you give me a hint of the algorithm you used for calculating the nodes positions?
