The Art of Graph Theory
 1. Graph theory is a fascinating branch of mathematics that deals with the study of graphs, which are mathematical structures used to represent relationships between objects. In the art of graph theory, we explore various concepts such as vertices, edges, paths, cycles, and connectivity. Graph theory has diverse applications in computer science, biology, social networks, and many other fields. Mathematicians and computer scientists use graph theory to solve complex problems such as network flow optimization, scheduling algorithms, and route planning. Understanding the underlying principles of graph theory can lead to innovative solutions and insights into a wide range of real-world problems.What is a graph in graph theory?A) A form of abstract art based on geometric shapes.B) A drawing or diagram representing mathematical functions.C) A mathematical structure consisting of vertices and edges.D) A type of bar graph used for data visualization.2.
