Open Source C++ Data Visualization Software for Linux

CoFlo generates Control-Flow Graphs from C and C++ source code. It can then output the graphs in a number of ways and perform various control flow analyses. NOTE: CoFlo has not been under active development for several years. At this time, I suggest you look into LLVM-based tooling to see if there is anything similar to CoFlo which will meet your needs.

ParTools allows the interactive analysis of a C program execution profile and data dependencies to facilitate the discovery and selection of suitable parallelization candidates in a manual parallelization process. The flow does not assume any specific parallelization technique, thus it can be broadly applied. The original (serial) C source is automatically annotated to trace the execution profile and data dependencies at run-time. The annotated program is then executed using a significant (but small) data set selected by the developer. The data collected is cross-referenced with the original source and can be interactively analyzed graphically to determine the best parallelization candidates and techniques.
