OOP AS2 and Complex Data Visualization

Ok, I’ve gotten it in my head to finally jump into object-oriented programming and what I want to create is something like the visual thesaurus or something linked on the [url=http://www.visualcomplexity.com/vc/]Visual complexity site.

So, I’ve seen Samuel Wan’s treemap, but that is written in AS1 and I’ve looked at the Java algorithms on the [url=http://www.cs.umd.edu/projects/hcil/treemap/]U of Maryland pages, but can anyone give me some suggestions of how to start this in flash 8, publishing to player 8, using object oriented best practices? Would this be a classic example of MVC? And if so, how would you go about it?
