How should I visualize the structure of my code? [closed]

Answer 1

Here is a non UML Tool which has very nice visualization features.

You can mapping the lines of code per class / method to colors / side lenght of rectangles. You can also show the dependencies between the classes.

The nice thing is, you can use Smalltalk scripting for displaying what you need: http://www.moosetechnology.org/docs/faq/JavaModelManipulation
