In this article, we will learn how to add markers to a Graph Plot in Matplotlib with Python. For that just see some concepts that we will use in our work.

• Graph Plot: A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.
• Markers: The markers are shown in graphs with different shapes and colors to modify the meaning of the graph.
