What are bar graphs and pie graphs strengths and weaknesses?

Bar graphs are effective for comparing discrete categories, making it easy to visualize differences in size or frequency. However, they can become cluttered with too many categories, which might confuse the viewer. Pie graphs Excel at showing proportions within a whole, providing a clear view of relative sizes. Nevertheless, they can be misleading if there are too many slices or if the differences between them are subtle, making it hard to interpret accurate values.
