What is the difference between pie chart and bar graph?

Pie charts show how much each category represents as a proportion of the whole, by using a circular format with different-sized “slices” for different percentages of the whole. Bar graphs use a series of rectangular bars to show absolute values or proportions for each of the categories.

What are the advantages of bar chart against a pie chart?

The bar/column chart excels at showing discrete data while comparing one data-point vs. another, while the pie chart is the classic way to show how various parts makes up a whole. Both make it easy to for readers compare values relative to each other.
