What are the limitations of Bar Graph?

Bar graphs are limited in their ability to represent complex data relationships, as they primarily display categorical data without showing trends over time. They can also become cluttered and difficult to interpret if there are too many categories or if the data values are close in magnitude. Additionally, bar graphs may oversimplify the data, potentially leading to misinterpretations if the scale is not appropriately chosen. Lastly, they do not convey information about the distribution or variability within the data.
