DDD is a graphical front-end to a command-line debugger.  DDD supports debuggers like GDB and CUDA-GDB, and may be usable with others.

Besides front-end features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.
