Introduction to Graph Theory by Richard J. Trudeau  Aimed at 'the mathematically traumatized,' this text offers nontechnical coverage of graph theory, with exercises. Discusses planar graphs, Euler's formula, Platonic graphs, coloring, the genus of a graph, Euler walks, Hamilton walks, more. 1976 edition.
