Graph nodes coordinates evaluation [closed]

Question

Which of these (https://stackoverflow.com/questions/492893/graph-drawing-c-library) libraries can be used to evaluate nodes coordinates? I mean I want to draw and manipulate graph by clicking on it to add some nodes or delete, and then evaluate coordinates using some lightweight library.

Prefferable languages: C++, C#, Java
