Define graph and digraph by using diagram
WebWhat is a digraph? A digraph is two letters that make one sound. The digraph can be made up of vowels or consonants. A trigraph is a single sound that is represented by three letters. Consonant digraphs are taught in Reception. There is then a whole range of vowel digraphs that are taught in Year 1. http://homepages.math.uic.edu/~leon/cs-mcs401-s08/handouts/graphs-intro.pdf

In formal terms, a directed graph is an ordered pair G = (V, A) where V is a set whose elements are called vertices, nodes, or points;A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the corresponding set named E instead of A), arrows, or directed … See more In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph that is made up of a set of vertices connected by directed edges, often called arcs. See more An arc (x, y) is considered to be directed from x to y; y is called the head and x is called the tail of the arc; y is said to be a direct successor of … See more The degree sequence of a directed graph is the list of its indegree and outdegree pairs; for the above example we have degree sequence ((2, 0), (2, 2), (0, 2), (1, 1)).

Figure 6.2. 1 is a digraph for r. Notice that since 0 is related to itself, we draw a “self-loop” at 0. The actual location of the vertices in a digraph is immaterial. The actual location of vertices we choose is called an embedding of a graph.
