Connect new neighbor nodes around a central node.
[ge]=CirclePlace(n,d,g,i)
quantity of neighbor nodes.
maximal radius from the central node.
initial network graph.
central node index.
union graph.
CirclePlace connects n nodes around the central node of index i within the original graph g. They are randomly placed inside a disc of radius d centered around the node i. The distance between any new nodes and the central node belongs to the range [d/2,d].
