Drawing Feynman diagrams via computer

[John E. Davis]

Does anyone know of an interactive graphics package that I can use to draw
Feynman diagrams? I know that such graphics packages exist for apple
computers but I am not aware of any for the sun workstations or for
graphics terminals using DI3000 graphics package. The program I have in
mind must be capable of drawing text charactors with different fonts as
well.
