Once installed, you can use its extensive libraries in your ''C++'' code or in the ''ROOT'' command line. If you don't like ''C++'' or pointers, it is also possible to use ''ROOT'' in ''python'', a.k.a. ''pyROOT''. This is definitely a good choice for doing simple things, such as making plots. | Once installed, you can use its extensive libraries in your ''C++'' code or in the ''ROOT'' command line.
