Definition: Graph is a mathematical representation of a network and it describes the relationship between lines and points . A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.

What is a graph simple definition?
1 : a diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables. 2 : the collection of all points whose coordinates satisfy a given relation (such as a function)
How do you explain a graph to a child?
- Line graphs have little dots represent the information. If you love connecting the dots, then a line graph will be your best friend! ...
- Circle graphs show a circle divided into slices representing different things. ...
- Graphs show you information as a visual image or picture.
What is a graph example?
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 . ... The definition of a graph is a diagram showing the relationships between two or more things. An example of graph is a pie chart.
What are the basic graphs?
A basic two-dimensional graph consists of a vertical and a horizontal line that intersects at a point called origin . The horizontal line is the x axis, the vertical line is the y axis. In simple line graphs, the x and y axes are each divided into evenly spaced subdivisions that are assigned to numerical values.
How do you describe a graph?
In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner . The points on the graph often represent the relationship between two or more things. ... We then represent the data using a bar graph.
What is a graph and its types?
In discrete mathematics, a graph is a collection of points, called vertices, and lines between those points, called edges. There are many different types of graphs, such as connected and disconnected graphs, bipartite graphs, weighted graphs, directed and undirected graphs, and simple graphs .
How do you identify a simple graph?
A simple graph is a graph that does not have more than one edge between any two vertices and no edge starts and ends at the same vertex. In other words a simple graph is a graph without loops and multiple edges. Two vertices are said to be adjacent if there is an edge (arc) connecting them.
What is a graph in reading?
Line graphs and bar graphs are both visual ways of representing two or more data sets and their interrelation. In other words, graphs are pictures that show you how one thing changes in relation to another . Learning to read graphs properly is a matter of interpreting which pieces of information go together.
What’s the purpose of a graph?
Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space . Do not, however, use graphs for small amounts of data that could be conveyed succinctly in a sentence.
What are the three types of graph?
Three types of graphs are used in this course: line graphs, pie graphs, and bar graphs .
What are the different parts of a graph?
- The Title. The title offers a short explanation of what is in your graph. ...
- The Legend. The legend tells what each line represents. ...
- The Source. The source explains where you found the information that is in your graph. ...
- Y-Axis. ...
- The Data. ...
- X-Axis.
What is the difference between a graph and a tree?
| No. Graph Tree | 1 Graph is a non-linear data structure. Tree is a non-linear data structure. | 2 It is a collection of vertices/nodes and edges. It is a collection of nodes and edges. |

What is simple graph with example?
A graph with no loops and no parallel edges is called a simple graph. The maximum number of edges possible in a single graph with ‘n’ vertices is n C 2 where n C 2 = n(n – 1)/2. The number of simple graphs possible with ‘n’ vertices = 2 n c 2 = 2 n ( n – 1 )/ 2 .
What is order and size of a graph?
Order of a graph is the number of vertices in the graph . Size of a graph is the number of edges in the graph.
