Vvidget_GG.framework and Vvidget_GS.framework part of OS X default install?

I downloaded some example code to draw a line graph in Cocoa. The example is not running because Vvidget_GG.framework and Vvidget_GS.framework do not开发者_StackOverflow exist. I searched in my /System/Library/Frameworks and /Library/Frameworks folders to add them to my project, but they are not there on my system.

Do these frameworks exist by default on OS X?

They are definitely not part of any Apple SDK — apparently, they’re sold by Vvidget.
