Graph theory is widely used in computer science, engineering and of course, mathematics. Wikipedia offers this definition and overview of Graph Theory (1). This next website from Mega-Math (2) reviews some of the Vocabulary of Graphs and highlights some applications for graph theory, such as the design of computer systems and games. Some additional applications for Graph Theory are discussed in this more technical book called Graph Theory with Applications (3). This website from Georgia Tech (4) discusses a proof that allows a user to create a map of the U.S. using just four colors. For a more involved explanation of Graph Theory, see this Graph Theory book by Reinhard Diestel (5). On this next website (6), Christopher P. Mawata of the University of Tennessee at Chattanooga offers a collection of Graph Theory Lessons for educators. The final website provides a short biography of a key figure in Graph Theory who recently passed away, Frank Harary (7).
