I've got an idea for your next book
There is a lot of material in suttas that may be presented as tables and charts.
Some suttas look just like reading aloud a table cell by cell. Structures of some other suttas are harder to visualize, though not impossible.
Dmytro made a dependent origination chart based on several suttas:http://dhamma.ru/lib/paticcas.htm
I think that visual rendering of sutta material may be useful, as modern people are more accustomed to grasping information from tables and charts than from mnemonic texts like suttas.
So, how do you feel about "Buddha's Charts"?
