Can we stop overlapping of nodes? I want my nodes not to overlap with each other.
I assume you’re talking about one of the layouts. Which layout? Which version of GoXam?
ForceDirectedLayout isn’t guaranteed to avoid overlapping nodes. It’s likely to avoid them when there’s enough room, but depending on the graph structure and the ForceDirectedLayout properties there might not be enough room to spread them out. You could try increasing the electrical repulsion between nodes and maybe increasing the lengths of the springs or decreasing the stiffness of the springs.
I think all of the other layouts guarantee that the laid-out nodes do not overlap.
