Hi Divyanshu Thanks very much for this valuable contribution. I have looked at the patch and it looks sensible so far, but I need to ask: are the cgraph and agraph libraries actually the same? Do we really not also need to patch the C code?
Anything you can do towards making Graphviz a runtime dependency only would be a big help. Indeed, any function calls to GraphViz will then need to be made via a function pointer instead of directly, and those function points will need to be determined using dlopen and associated functions.
