1. Attachment 01- Histogram
2. Attachment 02- Bar diagram

Main difference between bar diagram and histogram:

Bar diagram:

• It's 1 Dimensional
• Only length of bars is considered while comparison
• Width between 2 bars is always kept the same
• Width between a single bar is always equal

Histogram:

• It's 2 Dimensional
• Height and width of bars both are considered while comparison
• There no width between two bars.
• The width between a single bar depends on the range of class interval.
