OpenSCAD is a CSG (Constructive Solid Geometry) modeller for 2D or 3D.
It is not a line drawing program, neither in 2D nor 3D.

If you needed
three concentric circles for a drawing (with no filled areas) (such as
for a
graphic), you are out of luck.

In OpenSCAD, everything is a solid (in 2D or 3D). If what you want is a
line drawing tool, then OpenSCAD is the wrong choice.

Perhaps you could use D3.js library.
It's graph oriented but there's many other kind of example :

It's use SVG model.

I recently wrote a library which could help for your problem. It's about
lasercutting stuff with OpenSCAD, see

Imagemagick is good for some types of processing, but not for creating images
from scratch.

I'm looking for a tool where I can script things like this:

Start with a blank bitmap. Load another bitmap from disk. Draw a circle on
it, then invert what's in the circle. Paint the modified bitmap in several
positions on the screen. Draw a border of evenly spaced circles. Load a logo
bitmap from disk and put in the corner. Add some text in a new layer, set to
semitransparent and add to the main picture as a water mark. Convert the
result to greyscale.

Basically, a combined bitmap and vector tool, like a bunch of paint programs
out there, but with the mindset of OpenSCAD, where everything is scripted
and there is no GUI for drawing. Basically, scripted drawing for engineers.

Guess one can do most of that with a hand coded svg with embedded bitmaps and
possibly even scriptable canvas tag.
