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.
