ROOT is a modular scientific software framework. It provides all the
functionality needed to deal with big data processing, statistical analysis,
visualisation and storage. It is mainly written in C++ but integrated with
other languages such as Python and R. ROOT is widely used in high energy
physics, but also in other data analysis applications. It contains the
CINT (ROOT 5.x) or cling (ROOT 6.x) C/C++ interpreter and many other
classes for statistics, serialization, optimization, linear algebra,
graphics, GUI toolkit, and a complete visualization framework.
