How to interprete graphical output of DDG and DFG

[Sakaze]

Hi, I just searched for an explanation of the graphical output from DDG and DFG but I didn't find any.
So here are my questions to the DDG and DFG png output files:

• In DDG and DFG a node consists of 3 sections. For what does each section stand?
• What is the meaning of green colored nodes?
• How is a edge interpreted(in witch direction works the dependency)?
• What is the meaning of blue/black/red//green or doted edges in DDG and DFG?
• What is the meaning of "kill" of an edge or other markings?

Maybe you can add a legend for the graphical representation to the documentation.
Best regards :-)
