I'd like to not be restricted to projects and compiling, rather, just get stuff done from the ghci REPL. How could I, for example, alter your mycircle starter example to be done completely at the ghci REPL?

Yes, it's possible.  There is a generic function 'renderDia' which can be used to output an image, and many backends provide more specialized such functions, for example the SVG backend provides renderSVG:


So at the ghci prompt you could do something like

>>> myCircle = circle 1 :: Diagram B
>>> renderSVG "foo.svg" (mkWidth 400) myCircle

which would render the diagram to the file "foo.svg" with a width of 400.
