[Boost-users] Planar graph generator

I'm going to write a shell script or a C++ program which creates planar graphs, pipes them to my graph coloring program and lists successes and failures. After consulting the internet I found only three reasonable candidates for planar graph generators. Brendon McKay's plantri and fullgen Ledas graph_gen and Donald Knuth's Stanford Graph Base gb_plane . Any thoughts on which planar graph generator to use, or anything?
