Step-by-step explanation:
A graphical representation is a method in which a line or bars are made to represent the given data. Whereas a table representation is a method in which values are written numerically for a given set of data.
Basically, a graph helps by making it easy to determine the similarities and dissimilarities between different set of data. On the other hand, in a tabular representation each value needs to be checked in order to find the difference between two or more data sets.
