FWIW. ROOT is a data-analysis framework/toolbox that was originally developed by a few guys at CERN and is now used all over the work in research. Mostly in fundamental physics, but I believe there are a few companies that use it as well (see the website).
The papers application is another interesting example...
I guess gnuplot and xmgrace fall in a similar category. There must be specialised utilties/toolboxes in other fields as well, but I would not know where to look.
