"In mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects."
There are many types of graphs, including directed and undirected graphs, weighted graphs, bipartite graphs, and more.
Graph Fundamentals: This topic explains the basic concepts of graphs such as vertices, edges, and degrees.
Graph Classification: This topic covers the classification of graphs based on different criteria such as the number of vertices, edges, cycles, bipartite graphs, etc.
Directed Graphs: It explains the directed graphs and its properties such as indegree, outdegree, strongly connected components, etc.
Weighted Graphs: This topic explains the concept of weights for graphs, also known as capacity or cost associated with edges.
Trees: This topic explains the concept of trees, which are special cases of graphs, having no cycles and the properties defining them.
Spanning Trees: It talks about the concept of spanning trees, which are trees that include all the vertices of the parent graph.
Planar Graphs: It introduces planar graphs and their properties, including Euler's formula.
Graph Coloring: This topic explains the concept of graph coloring, where a graph can be colored in such a way that no two adjacent vertices have the same color.
Matching Theory: It covers the concept of matching in graphs, where a matching is a set of edges with no common vertices.
Graph Algorithms: There are various algorithms associated with graphs, including Kruskal's algorithm, Prim's algorithm, Dijkstra's algorithm, etc.
Graph Connectivity: This topic explains connectivity in graphs, including concepts like strongly and weakly connected graphs.
Graph Traversals: This involves various methods to traverse a graph, such as depth-first search and breadth-first search.
Graph Isomorphism: It covers the concept of isomorphism in graphs, where two graphs are isomorphic if they have the same structure but different labels.
Spectral Graph Theory: It introduces the connection between the eigenvalues and eigenvectors of a graph's associated matrix and its properties, such as connectivity and number of cycles.
Random Graphs: This topic explains the concept of random graphs, where edges are added randomly based on certain probabilities or distributions.
Networks: It discusses the concept of networks, which usually involve graphs where vertices represent nodes or points, and edges represent connections or relationships between them.
Applications of Graph Theory: Graph theory has numerous applications in various fields, including computer science, social network analysis, transportation and logistics, etc.
Bar Graphs: These are the most common type of graph used to represent categorical data using rectangular bars.
Line Graphs: Line graphs are used to represent changes in data values over time by connecting individual data points with a continuous line.
Scatter Plots: Scatter plots are used to represent the correlation between two variables by plotting pairs of data points on a two-dimensional plane.
Pie Charts: Pie charts are used to represent proportions of a whole by dividing a circle into different segments.
Histograms: Histograms are similar to bar graphs, but they are used to represent continuous data by dividing it into intervals or bins.
Gantt Charts: Gantt charts are used to represent project schedules by displaying the timelines and dependencies of different project tasks and milestones.
Box Plots: Box plots are used to represent the distribution of data by depicting the median, quartiles, and outlier values in the form of a box and whisker plot.
Network Graphs: Network graphs are used to represent complex systems and their relationships by using nodes and edges to depict connections between different entities.
Heatmaps: Heatmaps are used to represent the intensity of certain types of data values by using a color gradient to represent different levels of concentration.
Radar Charts: Radar charts are used to represent multiple variables by plotting them all on a circular grid and connecting their respective data points.
