The command 'frama-c -cg hello.dot hello.c' dump the syntactic callgraph 
in dot format into the file hello.dot. That is the very same graph than 
the one displayed in the GUI through Analysis -> Show callgraph.

For the record, this callgraph is syntactic: it ignores any function 
pointers. If your input program contains such pointers, you would 
compute the semantic callgraph which uses the results of the 'Value 
Analysis' plug-in to take function pointers into account. The command 
line is the same that the above one, but using option -scg instead of 
-cg. This semantic callgraph is not yet available through the GUI.

Hope this helps,
Julien
