graph The definition of a graph is a diagram showing the relationships between two or more things. An example of graph is a pie chart. Graph is defined as to create a diagram that shows a relationship between two or more things. An example of graph is to create a series of bars on graphing paper.

Definitions &Translations Typically, a graph is depicted in diagrammatic form as a set of dots for the vertices, joined by lines or curves for the edges. Graphs are one of the objects of study in discrete mathematics. The edges may be directed or undirected. For example, if the vertices represent people at a party, and there is an edge between two people if they shake hands, then this is an undirected graph, because if person A shook hands with person B, then person B also shook hands with person A.

Graph (abstract data type) A graph data structure consists of a finite (and possibly mutable) set of vertices or nodes or points, together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph.

Graph Theory: Definition and Properties A sub-graph is a subset of a graph G where p is the number of sub-graphs. For instance G’ = (v’, e’) can be a distinct sub-graph of G. Unless the global transport system is considered in its whole, every transport network is in theory a sub-graph of another.

Definitions and Examples A computer graph is a graph in which every two distinct vertices are joined by exactly one edge. The complete graph with n vertices is denoted by Kn. The following are the examples of complete graphs. The graph Kn is regular of degree n-1, and therefore has 1/2n(n-1) edges, by consequence 3 of the handshaking lemma.

chart Whether it's a kind of graph, a map, or even a piece of music, a chart is a visual display of information. As a verb, chart means to make that kind of display. Some words' meanings grow narrower over the centuries. But in the case of chart, which comes from the French charte and Latin charta, map, the meanings have grown a lot since the 1500s.

Graphs of Functions Defining the Graph of a Function. The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation. Example 1.

Graph (discrete mathematics) A finite graph is a graph in which the vertex set and the edge set are finite sets. Otherwise, it is called an infinite graph. Most commonly in graph theory it is implied that the graphs discussed are finite. If the graphs are infinite, that is usually specifically stated.

Graphs of Functions Graphs of functions are graphs of equations that have been solved for y! The graph of f(x) in this example is the graph of y = x2 - 3. It is easy to generate points on the graph. Choose a value for the first coordinate, then evaluate f at that number to find the second coordinate.

Presenting Data in Graphic Form A pie chart is a graph that shows the differences in frequencies or percentages among categories of a nominal or ordinal variable. The categories are displayed as segments of a circle whose pieces add up to 100 percent of the total frequencies. Pie charts are a great way to graphically show a frequency distribution.

- Axes. Graphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. 1  The x-axis may contain categories or numbers. 2  You read it from the bottom left of the graph.raphs have two axes, the lines that run across the bottom and up the side.

Definitions &Translations Freebase(0.00 / 0 votes)Rate this definition: In graph theory, the resistance distance between two vertices of a simple connected graph, G, is equal to the resistance between two equivalent points on an electrical network, constructed so as to correspond to G, with each edge being replaced by a 1 ohm resistance. It is a metric on graphs.
