Graphs and charts are common methods to get a visual inspection of data. Graphs and charts are the graphical summaries of the data. Graphs represent diagrams of a mathematical or statistical function, while a chart is a graphical representation of the data. In the charts, the data is represented by symbols.

The important features of graphs and charts are (1) Title: the title of charts and graphs tells us what the subject of the chart or graph is, (2) Vertical Axis: the vertical axis tells us what is being measured in the chart and a graph, and (3) Horizontal Axis: the horizontal axis tells us the units of measurement represented.

There are various mathematical and statistical software that can be used to draw charts and graphs. For example, MS-Excel, Minitab, SPSS, SAS, STATA, Graph Maker, Matlab, Mathematica, R, Exlstat, Python, Maple, etc.

Note that

• All graphs are charts, but not all charts are graphs.
• Charts present information in a general way.
• Graphs show the connections between pieces of data.
