Economics has been built on the foundation of visual elements, such as graphs and charts.<ref>{{cite journal |last1=Vazquez |first1=Jose J. |last2=Chiang |first2=Eric P. |title=A picture is worth a thousand words (at least): The effective use of visuals in the economics classroom |journal=International Review of Economics Education |date=September 2014 |volume=17 |pages=109–119 |doi=10.1016/j.iree.2014.08.006 }}</ref> Similar to the other aspects of why visual elements are used, graphs are used by economists to clarify complex ideas. Graphs simplify the process of visualizing trends that happen over time. Along the same lines, graphs are able to assist in determining a relationship between two or more variables. The relationship can determine if there is a positive correlation or negative correlation between the variables.<ref>{{Cite web|title=The 45-Degree Line of Economics Definition|url=https://bizfluent.com/info-8391714-45-degree-line-economics-definition.html|access-date=2021-01-30|website=Bizfluent|language=en}}</ref> A graph that economists rely heavily on is a time-series graph, which measures a particular variable over a period of time. The graph includes time being on the X-axis, while a changing variable is on the Y-axis.<ref>{{Cite web|title=Using Graphs and Charts to Show Values of Variables|url=https://2012books.lardbucket.org/books/macroeconomics-principles-v1.0/s24-03-using-graphs-and-charts-to-sho.html|access-date=2021-01-30|website=2012books.lardbucket.org}}</ref>
