Disclaimer: The first and second part of the question aims at the observational and creational skills of a student. Hence, the answer to these parts should be done by the students on their own.

Graphs are used instead of tables sometimes because visual presentation is more efficacious. Graphs provide us with the quick statistical analysis of the data. So, we convert the numerical data given in the table into a pictorial form for the ease of reading and understanding.
