Graphs

 Graphs are a great way to visualize data and display statistics. For example, a bar graph or chart is used to display numerical data that is independent of one another. Incorporating data visualization into your projects is essential when working with numbers statistics.

Bar Graph

A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips. Bar graphs are used to compare and contrast numbers, frequencies or other measures of distinct categories of data. Bargraph are used to compare things between different groups or to track changes over time.

Line Graph 

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. 

Pie graph 

Pie charts can be used to show percentages of a whole, and represents percentages at a set point in time. Unlike bar graphs and line graphs, pie charts do not show changes over time.

Scatter plot graph 

Scatter plots' primary uses are to observe and show relationships between two numeric variables. The dots in a scatter plot not only report the values of individual data points, but also patterns when the data are taken as a whole. Identification of correlational relationships are common with scatter plots.

A bubble chart is primarily used to depict and show relationships between numeric variables. The addition of marker size as a dimension allows for the comparison between three variables rather than just two.
