Maybe you wish to say 3D dimensional, as if you only mean dimensional,
then anything in this world including any types of graphs are
dimensional.

So if you do mean that OpenSCAD is 3D dimensional, well, it has that
capacity, but nothing prevents you being 2D dimensional.

See here for exporting files:
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/STL_Import_and_Export

For references of the simple drawing language, see here:
http://www.openscad.org/documentation.html?version=2015.03

I am using Emacs to simply write the drawing, then such can easily be
exported. It is possible to configure Emacs, if necessary, to open the
exported file and display it after saving such. So the OpenSCAD window
need not be seen at all.

Just use the automatic preview option in OpenSCAD, edit the file and
OpenSCAD will show the drawing after each saving of the file.

You do not need to launch the OpenSCAD for quick previews, you could
launch it from command line, upon the emacs save hook so that file is
each time generated as you wish.

Try following, adapt the font name.

module logo(logo,size) {
     rotate([90]) {
	  color("gold") text(logo, font = "Impact", size = size, haling = "center", valign = "bottomline");
     }
}

logo("Emacs");
