The garbage collector is switched to debug mode (all identified garbage is stored in `gc.garbage`) and the garbage collector is invoked. The collected objects are then illustrated in a directed graph. Large graphs can be reduced to the actual cycles by passing ``reduce=True`` to the constructor. It is recommended to disable the garbage collector when using the ``GarbageGraph``. >>> from pympler.garbagegraph import GarbageGraph, start_debug_garbage >>> start_debug_garbage() >>> l = [] >>> l.append(l) >>> del l >>> gb = GarbageGraph() >>> gb.render('garbage.eps') True FTcCs8|rttjn tdtt|tj|dS)z Initialize the GarbageGraph with the objects identified by the garbage collector.
