What are followed vs non-followed links in Domain Analyis report?

[seanuk]

I'm new to SEOMoz and wondering if some nice person can put this into plain English for me?

On the Competitive Domain Analysis report there are green follow / no-follow links and blue followed / non-followed linking root domains?

what is the context of the green & blue circles? is there a better or worse visual representation that I should aim for - more dark green, more light green or about half & half.

thanks in advance
