Why is graph theory useful?

Graph Theory is ultimately the study of relationships. Given a set of nodes & connections, which can abstract anything from city layouts to computer data, graph theory provides a helpful tool to quantify & simplify the many moving parts of dynamic systems.

How is graph theory used in real life?

In the real-world, graph theory is used in the internet field, Google maps/ Yahoo maps, social media, web Page searching, City Planning, Traffic Control, Transportation & Navigation, Travelling Salesman Problem, GSM mobile phone networks, Map colouring, time table scheduling etc.

What is the importance of learning graph theory and its applications?

Graph Theory can model and study many real-world problems and is applied in a wide range of disciplines. In computer science, graph theory is used to model networks and communications; Google search, Google maps and social medias all use it. It is used in chemistry to model molecules and in biology to study genomes.

Why are graphs important in real life?

Visual presentation of data makes it easier to understand large amounts of data, trends, and relationships. The use of graphs in daily life also helps in making an analysis. For example, it provides structure in assessing performances, sales, and even deadlines. Graphs also help make calculations easier.
