Graph (discrete mathematics) A simple graph, as opposed to a multigraph, is an undirected graph in which both multiple edges and loops are disallowed. In a simple graph the edges form a set (rather than a multiset) and each edge is an unordered pair of distinct vertices.

Graph Theory Glossary Informally, a graph is a finite set of dots called vertices (or nodes) connected by links called edges (or arcs). More formally: a simple graph is a (usually finite) set of vertices V and set of unordered pairs of distinct elements of V called edges. Not all graphs are simple.

- Discrete and Continuous Graph This will be a very basic definition but understandable one. A graph is discrete when one (or both) of the variables has discrete entries, its means that are entered number, without decimal part, so the graph has no continuity, the trace will be broken parts, not a single one.

Inclined plane: A sloping surface, such as a ramp.

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.

Tree A tree is a mathematical structure that can be viewed as either a graph or as a data structure. The two views are equivalent, since a tree data structure contains not only a set of elements, but also connections between elements, giving a tree graph. Trees were first studied by Cayley (1857). McKay maintains a database of trees up to 18 vertices, and Royle maintains one up to 20 vertices.

The interconnected objects are represented by mathematical abstractions called vertices, and the links that connect some pairs of vertices are called edges.

- Since this graph only has one set of data, a key is not needed. Interpreting Graphs Remember that a scientific graph is usually a straight line or a curved line-not connect-the-dots. Each type of line represents a certain relationship between the two variables.

Graphs and Charts 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.

Bar graphs with vertical bars are sometimes called vertical bar graphs. A bar graph will have two axes.

Plot (graphics) Plot (graphics) Scatterplot of the eruption interval for Old Faithful (a geyser). A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a mechanical or electronic plotter. Graphs are a visual representation of the relationship between variables, very useful for humans who can quickly derive an understanding which would not come from lists of values. Graphs can also be used to read off the value of an unknown variable plotted as a function of a known one. Graph

Bar Graph A bar graph (also known as a bar chart) is a diagram that uses proportional-width bars to compare data among categories. A bar graph may run horizontally or vertically. The important thing to know is that the longer the bar, the greater its value. Bar graphs display data in a way that is similar to line graphs. Line graphs are useful for displaying smaller changes in a trend over time. Bar graphs are better for comparing larger changes or differences in data among groups. Bar graphs have three key attributes.

- Each object in a graph is called a node (or vertex) . Corresponding to the connections (or lack thereof) in a network are edges (or links) in a graph. Each edge in a graph joins two distinct nodes. More formally, we define a graph G as an ordered pair G = (V, E) where. 1  V is a set of nodes (vertices).
