R programming has multiple libraries which can be used to create charts like Bar charts, pie charts, histograms, box-plots etc. A bar graph or a bar chart is the representation of data in bars. On other hands, a pie chart is the representation of data or values as sectors within the circle each represented with a different color to distinguish them. Box-plot is used for getting information about possible outliers in the data sample. Various ways to save plots as images has also been explained in the unit.
