I'm 100% for this proposal. Not necessarily in Phobos -- but having such a tool available for quick & easy graphical output, such as drawing a function's curve, is definitely a great idea.

Now, the PureBasic example does this via a GUI/event loop window. It's not what I have in mind for my use cases. Rather, I would be in favor of a simple graphic frame that could be used like in good old times we used to draw directly on the video -- when this was easy to do, just using x,y pixel coordinates. Optionnally, a set of plotting/drawing routines, including vector image primitives.
(An inspiration for this may be Logo.)

I have no idea how to implement the base graphic frame, but once it's in place, I would certainly help in feeding the module with useful routines.
