Which software to use to generate a picture of a giant graph?

Question

I have a program in c++, done with graph representation with adjacency list, however, there are more than 2 million nodes in it. Is there any software that has a text format, that I can generate from my program, and import into that software to generate an image?

Answer 1

Make your software generate an archive in the pattern graphviz. It is a "de facto" standard and several software will be able to open it.
