Graph

A representation of numbers signifying different data sets. Graphs are vitally important in tracking past performance of economic data with the aim of predicting its future behavior. For example, a government agency may create a graph of unemployment claims over time. If claims have trended downward, the agency may predict that unemployment may remain low. Graphs are also crucial for technical analysts, who use them to track securities' performance to help make investment decisions. Graphs are also known as charts.

graph

a means of portraying data in pictorial form that shows the relationship between an INDEPENDENT VARIABLE and a DEPENDENT VARIABLE by labelling and scaling the two axes of the graph to represent the two variables, plotting joint values of the two in the space between the axes and joining these values with a line. Frequently, graphs show time as the independent variable, depicting by means of a line how the dependent variable has changed over time.
