Networkx is not based on graphviz.

Not sure what exactly you mean. you will have to enter the nodes somehow
- afterwards you can visualize them. 

Do you mean you would like to have a GUI for entering nodes and edges?
I see two options: (1) write a GUI to do that (2) use an existing graph
editor and use networkx or something like that for analysis.

 - Look at the source code for networkx.
 - Alternatively, basic graph algorithms can be found in many general 
   algorithm books.  
 - More specific stuff e.g. in A. Gibbons "Algorithmic Graph Theory".
