I just use a little X-library that I have for doing very simple graphics
under X -- it draws and erases dots, lines, and boxes. That's enough for
simple scientific visualization. I'll send you a copy, and if anyone
else is interested... (For instance, I got a "real-time" viewer for
a simple NlogN code working in less than an hour.)
