Good synthesis of graph theory

Looking for a synthesis of graph theory to better understand the mechanisms involved in new technologies (big data, optimum path finding), boosted by the phenomenal capacity calculation, I turned to the book.

Technique, it requires some solid bases. After an initial effort to delve into reading (the introduction is very well done and should be read carefully), the purpose is clear and interesting. This book helps to sort graphs techniques and choose the most suitable algorithms. To implement them, the book will likely be completed other readings.
