This is a ripoff. Save your money. I have seen charts published by BarCharts and free ones provided by Java Report. I expected this to be as good, but no where near.
I wonder publishers like AW can publish such thing and put up a list price of USD 5.95.
Of course that is the negatives of buying some thing without seeing. I dont see how some other readers found it useful.
Rather than spending money on this, one is just better of copying a few pages of Nutshell books and pasting on the wall.
A free poster from Java Report just came in. That is much better.
