Draw a set of diagrams representing the modules and classes in the system. We draw one diagram for each file, and one for each toplevel class or module. This means there will be overlap. However, it also means that you'll get better context for objects.
To use, simply
d = Diagram.new(info) # pass in collection of top level infos d.draw
The results will be written to the dot
subdirectory. The
process also sets the diagram
attribute in each object it
graphs to the name of the file containing the image. This can be used by
output generators to insert images.
Draw the diagrams. We traverse the files, drawing a diagram for each. We also traverse each top-level class and module in that file drawing a diagram for these too.
