# Set minimum edge separation for SpringElectricalEmbedding

I have a graph with nodes that themselves are images of graphs. When there are many nodes in the graph the nodes are placed too close to one another and so the images overlap, preventing the edges from being seen.

I would like to set some minimum separation between nodes so that this stops happening. I have attempted to alter the SpringElectricalEmbedding's options, such as changing "RepulsiveForcePower", but to no avail.

The code I am using is the following, with NodeGraphImgs providing the node images and edges the graph's structure:

Graph[edges[[;; , 1]],
VertexShape -> NodeGraphImgs,
VertexSize -> Scaled[{0.12, 0.12}],
VertexLabels -> None,
EdgeStyle -> Thick,
AspectRatio -> 1,
GraphLayout -> {"SpringElectricalEmbedding",
"RepulsiveForcePower" -> -1},
