Graph (data structure) A labeled graph of 6 vertices and 7 edges.
In computer science, a graph is an abstract data structure that is meant to implement the graph concept from mathematics.
A graph data structure consists mainly of a finite (and possibly mutable) set of ordered pairs, called edges or arcs, of certain entities called nodes or vertices. As in mathematics, an edge (x,y) is said to point or go from x to y. The nodes may be part of the graph structure, or may be external entities represented by integer indices or references.
A graph data structure may also associate to each edge some edge value, such as a symbolic label or a numeric attribute (cost, capacity, length, etc.).
Tree, Graphs are the types of nonlinear data structure.
A tree.
The data structures are user defined data types specifically created for the manipulation of data in a predefined manner. Examples of data structures would be stacks,queues,trees,graphs and even arrays(also reffered as data structure)
bar graphs use categorical data
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.
Graphs visualize data allowing the brain to interpret a large data set quickly and infer trends.
They both show a set of data. Line graphs show data over time. Pie graphs show percentages in data.
line graphs, bar graphs,and circle
graphs are to compare and contrast data
bar graphs are for measuring points of data.
Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.
Circle graphs show data in a circle, while line graphs are akin to join the dots, and a bar graph shows data in vertical or horizontal bars, but all three show the same data results.
