Hi Parvez ,
First , you have to decide what you wish to present , only thereafter we can show how to do it.
Do you want an interactive presentation or just a static report ?
Do you want comparisons ? If so , do you want a comparison of just one area with another , with a possibility of changing the comparison areas , or do you want all areas in one chart ?
Do you want a presentation of the top 5 and bottom 5 customers for each area / each year ?
Make a detailed to-do list , and then we can see how much of it , and how it can be implemented.
