Question about general relativity and the standard model?

From general relativity, i know that spacetime can be considerably bent around a black hole, and that causes light to follow the path that it does, that is, no path. and then perhaps no one knows its path or maybe its path isnt worth talking about. but what about gravitons? they do come from a black hole. do they do the bending of spacetime? how do you visualize that? how do they escape a black hole? maybe they cannot attract themselves into the hole? any input would be appreciated. thanks.
