We shall learn about traversing a graph in the coming chapters. To know more about Graph, please read Graph Theory Tutorial. In the following example, ABCD represents a path from A to D.ДЇollowing are basic primary operations of a Graph в€’ДЄdd Edge в€’ Adds an edge between the two vertices of the graph.Дisplay Vertex в€’ Displays a vertex of the graph. The difference between realistic and logical visuals is a common one in graphical representations. For example, a bar graph allows data stakeholders to visually show a wide range of data, which not only improves understanding but also makes things easier for the merchant. Path в€’ Path represents a sequence of edges between the two vertices. Pictograph is a term for a visual or pictorial representation of data.

In the following example, B is adjacent to A, C is adjacent to B, and so on. Here AB can be represented as 1 at row 0, column 1, BC as 1 at row 1, column 2 and so on, keeping other combinations as 0.ДЄdjacency в€’ Two node or vertices are adjacent if they are connected to each other through an edge. We can use a two-dimensional array to represent an array as shown in the following image. In the following example, the lines from A to B, B to C, and so on represents edges. B can be identified using index 1 and so on.Д®dge в€’ Edge represents a path between two vertices or a line between two vertices. We can represent them using an array as shown in the following image. In the following example, the labeled circle represents vertices. Vertex в€’ Each node of the graph is represented as a vertex. Before we proceed further, let's familiarize ourselves with some important terms в€’ We can represent a graph using an array of vertices and a two-dimensional array of edges.

Mathematical graphs can be represented in data structure. Take a look at the following graph в€’Д® = Graph Data Structure The interconnected objects are represented by points termed as vertices, and the links that connect the vertices are called edges.ДЇormally, a graph is a pair of sets (V, E), where V is the set of vertices and E is the set of edges, connecting the pairs of vertices. A graph is a pictorial representation of a set of objects where some pairs of objects are connected by links.
