Spectral Embeddings (Distances -> Coordinates)

From: andrew cooke <andrew@...>

Date: Tue, 13 May 2014 19:51:34 -0400

This is really weird.  See section 1.3 of
http://www.cs.yale.edu/homes/spielman/eigs/lect1.pdf

This is an answer to the question at
http://www.reddit.com/r/compsci/comments/25gxm3/draw_a_map_given_distances_between_cities/

What is being plotted in the first link is related to the eigenvectors of a
matrix that describes the graph, using just -1 for neighbours and the degree
along the diagonal.  Weird.
