const { overlap_scaling } = attribute;
When overlap=prism, the layout is scaled by this factor, thereby removing a fair amount of node overlap, and making node overlap removal faster and better able to retain the graph's shape.
If overlap_scaling is negative, the layout is scaled by -1*overlap_scaling times the average label size. If overlap_scaling is positive, the layout is scaled by overlap_scaling. If overlap_scaling is zero, no scaling is done.
