From Geoff Anders, of Leverage Research (http://www.leverageresearch.org/)

For people doing goal factoring - or for people making any sort of box-and-arrow diagram - I recommended the program yEd. It is available here: http://www.yworks.com/en/products_yed_about.html

After you install it, I highly recommend setting up the defaults in the following way:

1. Open yEd.
2. Create a new document.
3. Click the white background; a small yellow square should appear on the canvas.
4. Click the small yellow square so as to select it.

% MonitorAssignment( F, names, valNames, E ) - Pretty prints all the 
%   marginals for an assignment
%
%   F contains the struct array of factors
%   names contains the variable names
%   valNames contains the assignment names for each variable, 
%    as seen in SAMIAM
%   E is an N-by-2 cell array, each row being a variable/value pair. 
%     Variables are in the first column and values are in the second column.
