Hi Matt,
It's not for nothing that I like to have feedback :)
You can give a look at the population demo to see the underlying table,
just disable js and you'll see the table.
The table must not have a rigid structure, the options dataCell,
labelCell and colorCell let you specify the number of the columns
(counting from 0, which is the first column) in which these data can be
found.
Taken from the doc:
To create a Treemap of dimensions 640x480 starting from the tables in
the page, retrieving the descriptions from the 3rd column and the data
from the 5th:
jQuery("table").treemap(640,480,{labelCell:2,dataCell,4});

As I've just said, The table layout is not so important, as long you set
the right options.
I can't help, I need more informations. Could you provide a sample table
to make some tests?

Oh, that would be a nice refactoring. I'll keep it in the todo list but
as I wrote this plugin with jQuery in mind, I think it's not a priority.
By the way what kind of different layouts do you have in mind?

Great! Let us know when you'll do it.
