Advantages: compares data across categories

Disadvantages: it can only compare one set of data and depending on the intervals, it can be inaccurate2)

Advantages: it compares two sets of data across categories

Advantages: it compares changes in data over time

Disadvantage: when the symbols are cut, you can't tell how much of the symbol they have taken off

5)Circle Graph

circle graph's are best for comparing categories to the whole using percents.

Disadvantage: it takes a long time to make and very complicated to construct
