The cone of Euclidean distance matrices and its geometry is described in, for example, [11, 59, 71, 111, 112]. Using semidefinite optimization to solve Euclidean distance matrix problems is studied in [2, 4]. Further theoretical results are given in [10, 13]. Books and survey papers containing a treatment of Euclidean distance matrices in-
Given a partially-specified symmetric matrix A with zero diagonal, the Euclidean distance matrix completion problem (EDMCP) is to determine the unspecified entries to make A a Euclidean distance matrix. We survey three different approaches to solving the EDMCP.
grs performs Euclidean Distance Matrix Completion using the guided random search algorithm of Rahman & Oldford. Using this method will preserve the minimum spanning tree in the partial
3.1] A Euclidean distance matrix, an EDM in RN×N +, is an exhaustive table of distance-square dij between points taken by pair from a list of N points {xℓ, ℓ=1...N} in Rn; the squared metric, the measure of distance-square: dij = kxi − xjk 2 2, hxi − xj, xi − xji (1037)

One way to highlight clusters on your distance matrix is by way of Multidimensional scaling. When projecting individuals (here what you call your nodes) in an 2D-space, it provides a comparable solution to PCA.
