Graphical Analysis is a tool for science students to collect,
graph, and analyze data.
The primary advantages of graphical representation of data are:
Facilitates and improves learning:
graphics make data easy to understand
and eliminate language and literacy barriers.
Understanding content: visuals are more effective than text in
human understanding.

Scatterplots show many points plotted in the Cartesian
plane.
Each point represents the values of two variables.
One variable is chosen in the horizontal axis and another in
the vertical axis.
The simple scatterplot is created using the plot() function.

A line chart is a graph that connects a series of points by
drawing line segments between them.
These points are ordered in one of their coordinate (usually
the x-coordinate) value.
Line charts are usually used in identifying the trends in data.
The plot() function in R is used to create the line graph

R Programming language has numerous libraries to create charts and
graphs.
A pie-chart is a representation of values as slices of a circle with
different colors.
The slices are labeled and the numbers corresponding to each slice is
also represented in the chart.
In R the pie chart is created using the pie() function which takes
positive numbers as a vector input.
The additional parameters are used to control labels, color, title etc

dotchart() function in R Language is used to create a
dot chart of the specified data.
A dot chart is defined as a plot which is used to draw a
Cleveland dot plot.

A bar chart represents data in rectangular bars with length
of the bar proportional to the value of the variable.
R uses the function barplot() to create bar charts.
R can draw both vertical and Horizontal bars in the bar
chart.
In bar chart each of the bars can be given different colors

It's also possible to save the graph using R codes as
follow:
Specify files to save your image using a function such as
jpeg(), png(), svg() or pdf().
Additional argument indicating the width and the height of
the image can be also used. Create the plot.
