First of all it is something strange in the definition of colModel which you post. For example, the text like colModel": is definitively wrong. It is difficult to say something about the code if it contain a lot of errors (probably errors of formating, but a reader don't know your original code).
If you have problems to format the data, just post what you have and other people will be able reformat your question.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
