Bar Graph- Advantage: Shows which categories has the most or least
Disadvantage: The intervals might make the data very close, even if it's far
Double Bar Graph- Advantage: Compares two sets of data and shows which is better
Circle Graph- Advantage: Shows data as a percent
Disadvantage: Data won't be as accurate as a percent
Line Graph- Advantage: Shows the data overtime
Disadvantage: Can only be used for data overtime
Pictograph- Advantage: Can be easily identified
Disadvantage: Hard to identify if it's not a whole or half
