Interesting figure. If you cut out the options with poor runtime performance, you are left with Machine code (which almost no use for source code), Assembly (which is not too bad for RISC architectures, but really horrid for CISC targets like I86_64). C, which is a symbolic substitute for assembly language, a subset of C++ that is basically C, and Fortran. Fortran is the only one in the list I would consider a “high level” language.
