What's kind of graph?

[supeeti]

Hi all,

I have some problems with something that may be called "graph".
My program produces the results that look like the picture as follow



In this picture, there are 4 results which each result is composed of data node.  There is only one direction from left to right, no loop.

The first question is, what kind of this graph? Directed graph or else?

Afther I have the results. I need to do something to get new result like the picture as following.  Someone said me "factorize", I don't know.





So, the second quesiton, Which technique or algorithm or methodology are used for "factorize".


thanks

I'm not sure if u still need a solution to this problem.
If so let me know your requiremnts in detail .
If you can make it more clear what is the requirement of your final graph?

thnx
