ggplot2 is an open-source data visualization package for the statistical programming language R.Created by Hadley Wickham in 2005, ggplot2 is an implementation of Leland Wilkinson's Grammar of Graphics—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a ...

3D graphics have become so popular, particularly in video games, that specialized APIs (application programming interfaces) have been created to ease the processes in all stages of computer graphics generation.
The ROSE compiler framework, developed at Lawrence Livermore National Laboratory (LLNL), is an open-source software compiler infrastructure to generate source-to-source analyzers and translators for multiple source languages including C (C89, C99, Unified Parallel C (UPC)), C++ (C++98, C++11), Fortran (77, 95, 2003), OpenMP, Java, Python, and PHP.
The Edison Design Group (EDG) is a company that makes compiler front ends (preprocessing and parsing) for C++ and formerly Java and Fortran. [2] [3] Their front ends are widely used in commercially available compilers and code analysis tools.
Cfront had a complete parser, built symbol tables, and built a tree for each class, function, etc. Cfront was based on CPre, a C compiler started in 1979. As Cfront was written in C++, it was a challenge to bootstrap on a machine without a C++ compiler/translator. Along with the Cfront C++ sources, a special "half-preprocessed" version of the C ...
It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C programming language. [1] It was extended to compile C++ in December of that year.
