Arun, wonderful. 

Since, initially the specific number may not matter, why not devide the
areas into 1, 2, 3, 4, 5, --- 8.  this way the distribution becomes very
clear.  I completely agree that this dataset is very useful and we
should try to create a layer on OSM.

btw, since postal codes are common in other parts of the world, can you
point me to other visualizations of postal codes?
