For a connected graph of graph diameter
, the graph distance-
graph
for
, ...,
is a graph with the same vertex
set and having edge set consisting of the pairs of
vertices that lie a graph distance
apart. It is therefore the case that
(Brouwer et al. 1989, p. 437).
Graph distance graphs differ from Euclidean distance graphs in that the former are constructed based on graph distance between vertices, while the latter are constructed based on Euclidean distance.
