Debuggers aren't always the best tool for figuring out control flow - accidentally step over something and you can miss it - but they are useful to explore the map of data in memory. Some debuggers let you expand out the map hierarchically, others use separate windows (e.g. the old Borland IDE Debug Inspector windows). For exploring control flow, an instrumenting profiler is really useful, if you can easily isolate a representative code run.
