There are a lot of other textual source code for graphics, in addition 
to .pbm. But it seems you want direct generation of images in the screen 
instead of creating graphic files for later inspection.

Perhaps a possible approach could be to pipe awk output to some 
interpreter that draws the image on screen. For instance, you can pipe 
awk output to a Tcl/Tk intepreter (tclsh/wish), and send commands for 
creating and draw elements in a canvas widget.

This way the screen image could be modified on the fly, I think.

HTH.
