Neovis rendering/ stabilization issue

I am trying to generate similar to GoT visualization on neovis GitHub page using similarly looking data.
Managed to that but the node keeps on moving until I click stabilize button manually.
Every time I try to move a node, loop rendering is kicking in.
Is there any way to manually move nodes around for better visualization?
Here are links for sample data files, cypher queries to load the data and HTML file for viz
New to Neo4j & neovis. Any help is much appreciated.
